Power management integrated circuits (power management ICs or PMICs or PMU as unit) are integrated circuits for power management. Although PMIC refers to a wide range of chips (or modules in system-on-a-chip devices), most include several DC/DC converters or their control part. A PMIC is often included in battery-operated devices such as mobile phones and portable media players to decrease the amount of space required.
Overview[edit]
The term PMIC refers to a class of integrated circuits that perform various functions related to power requirements.A PMIC may have one or more of the following functions:[1]
- Power-source selection
- Power sequencing
- Miscellaneous functions
Power management ICs are solid state devices that control the flow and direction of electrical power. Many electrical devices have multiple internal voltages (e.g., 5 V, 3.3 V, 1.8 V, etc.) and sources of external power (e.g., wall outlet, battery, etc.), meaning that the power design of the device has multiple requirements for operation. A PMIC can refer to any chip that is an individual power related function, but generally refer to ICs that incorporate more than one function such as different power conversions and power controls such as voltage supervision and undervoltage protection. By incorporating these functions into one IC, a number of improvements to the overall design can be made such as better conversion efficiency, smaller solution size, and better heat dissipation.[2]
Features[edit]
A PMIC may include battery management, voltage regulation, and charging functions. It may include a DC to DC converter to allow dynamic voltage scaling. Some models are known to feature up to 95% power conversion efficiency. Some models integrate with dynamic frequency scaling in a combination known as DVFS (dynamic voltage and frequency scaling).
It may be manufactured using BiCMOS process. They may come as QFN package. Some models feature I²C or SPI serial bus communications interface for I/O.
Some models feature a low-dropout regulator (LDO), and a real-time clock (RTC) co-operating with a backup battery.
A PMIC can use pulse-frequency modulation (PFM) and pulse-width modulation (PWM). It can use switching amplifier (Class-D electronic amplifier).
IC manufacturers[edit]
Samsung Semiconductor, Ricoh Electronic Devices, Power Integrations, STMicroelectronics, Infineon Technologies AG, Intel, Marvell Semiconductor, Qualcomm, MediaTek, IXYS, Freescale Semiconductor,[3]Dialog Semiconductor, Silicon Mitus,[4]Exar, International Rectifier, Intersil, Cypress Semiconductor, Maxim Integrated Products, Linear Technology, Renesas Electronics, Rohm Semiconductor, ON Semiconductor, Texas Instruments, Torex Semiconductor,[2] and Asahi Kasei Microdevices are some of many manufacturers of PMICs.

Do you use suction cup windshield mounts to support your GPS or smartphone while driving? Did you know these mounts are illegal in many states? In fact, they are illegal in almost 70% of the United States!
Surprised? That may be because these laws aren’t always highly enforced, however, we can’t ignore them. Distracted driving is a top cause of automobile accidents. ProClip wants you to put safety first and keep both hands on the wheel. Read on to find a safe, legal mounting solution for the state(s) in which you drive.

States with Laws that Restrict Windshield Mounting Location
There are a handful of states in which suction cup windshield mounts are legal, but the law states specific requirements on where the GPS unit or smartphone can be mounted on the windshield.
Restrictions on Type of Device
Other states restrict the type of device that is allowed to be mounted onto the windshield. Typically, GPS devices or other devices that display pertinent information to the driver are allowed, but they still cannot obstruct the driver’s view of the roadway.

Placement on the Windshield
In the states below, GPS systems, toll payment systems and other safety monitoring equipment are permitted only when mounted as close to the bottom of the windshield as possible. Certain qualifications of these devices differ from state to state, so please check to see what your state allows.
- Arizona
- Arkansas
- California
- Hawaii
- Indiana
- Maryland
- Minnesota
- Utah
- Vermont
- Wyoming

- Alaska
- Iowa
- Kansas
- Kentucky
- Massachusetts
- Mississippi
- Missouri
- Nevada
- Ohio
- Pennsylvania

ProClip Suction Cup Mounting Solution
Our suction cup mount can easily be attached to your windshield, but the mount also comes with a 3M adhesive disk so you can attach the suction cup to your dashboard or console (shown below).
If Not the Windshield, Where Can You Mount Your Device?
Dashboard and Console Mounting Solutions
An alternative to mounting on your windshield is to use a dashboard mount or console mount for your phone or GPS. However, make sure to check the laws in your state on any specific rules that may prohibit you from mounting devices in other locations.
ProClip mounts are vehicle and device specific. We design each dashboard mount to fit seamlessly into the grooves of your dashboard, so there is no need to worry about damaging your vehicle. Not only are our mounts a great legal option, they are also the safe option. Having your phone or GPS securely mounted within reach will keep you less distracted while driving. Not convinced? Just ask our customers! 86% of our customers say they are a safer driver since installing their ProClip mounting solution.
We also offer adapter plates which allow you to attach your own GPS holder to one of our vehicle-specific dashboard or console mounts. Adapter plates are an easy way to transform the suction cup mount into a legal mounting option for the states that do not allow windshield mounts.
Be an informed driver. Do you know if your state bans cell phones or texting while driving? Check out our blog on cell phone driving laws by state. Keep informed by following our driver safety topics and tips.
