PMIC Selector by building block or application processor.

Parametric search for Power Management IC (PMIC), also known as Power Management Units (PMU). Search 150+ products from 20+ manufacturer for a wide range of PMIC products. Starting simple with a 2-channel PMIC like 1-channel  DC/DC converter plus 1 LDO or a 2-channel   DC/DC converter all the way up to a 58-channel PMIC with battery charger, USB-OTG control, 10 DC/DC converter, 20 LDO and many more building blocks.

PMIC combinations

Power Management IC with focus on power rails can be usually divided into 2 families. The ones with a battery charger and the ones without a battery charger.

PMIC with battery charger are usually dedicated for portable applications to power a special kind of application processor. If a PMIC and its power rails, output voltages, sequencing and so on is optimized to a dedicated application processor, they are called companion PMIC. The battery charger is usually optimized for a 5.0 V wall plug rail or a 5.0 V USB input for their 1-cell Li-ion battery and therefore the maximum input voltage is limited to 6.0V. The power rails can consist of any combination and any number of DC/DC converter and LDO. There are some products which can handle higher input voltages, like PMIC for 2-cell Li-Ion systems and a few which can withstand up to 40 V input voltage.

PMIC without a battery charger can be used in both worlds, the portable application or a system powered one. Everything else is very similar and we call them generic PMIC. This applies also to PMIC with battery charger but no focus a on given application processor. Due to the missing battery charger, the vast majority of the generic PMIC can only handle input voltages of 6.0 V or below (with very few exceptions).

PMIC Selector and parametric PMIC selection 

PMIC Selector guide

The PMIC Selector search filter are split into 4 groups.

  • First: Application focus.
    • A quick filter to search for companion PMIC or generic PMIC. Additionally it can be searced for common dual, triple or quad channel +/- split rail PMIC.
  • Second: Power building blocks.
    • Practically each PMIC power building block can searched for like battery charger, fuel gauge, DC/DC converter, DC/DC controller, LED driver, Charge Pump or LDO.
  • Third: Auxiliary building block.
    • Non-power building blocks can be searched for like audio codec, headphone amplifier, A/D converter, touchscreen, RTC or number of available GPIOs.
  • Forth: Misc.
    • Additional PMIC features can be searched like type of interface, adapter detection, power path management and output settings.
