PM1001Q20VR Datasheet | AiT Semiconductor

Ai T Semiconductor Inc. .ait-ic. PM1001 POWER MANAGEMENT UNIT (PMU) FOUR SEGMENT INDICATOR, SINGLE-CHIP POWER BANK DEDICATED IC DESCRIPTION Features PM1001 includes a programmable high efficiency BUCK charger, four LED battery indicators, a Torch LED driver, a high efficiency Boost converter, and an over discharge protector. It is suitable for single-cell lithium-ion/lithium polymer battery charge and discharge management, and can be widely used in power bank, handheld devices, PDA, smart phones and so on. It integrates high efficiency synchronous BUCK battery charge management, the maximum charging current up to 2A; the integrated boost DC/DC can output the maximum discharge current reaches 1.5A, and intelligent judgments load insertion and removal, automatic boost and automatic shutdown; the integrated battery detection and 4 -segment display, both in the state of charge or discharge, can effectively indicate the remaining power of the battery. By the external key button, it can easily control the boost switch on and Torch On/off. Torch LED can output maximum 50m A of current. PM1001 also integrates a battery temperature detection, low battery voltage protection, output over current /over voltage/short circuit protection circuit to ensure that chip and system security. - One Key Control - 2A charge current - 1.5A discharge current - 50m A Torch application integration - Automatically start when the device is plugged into power bank(need other circuits) - Automatically shut down when device is full or be plugged out 16 seconds - 4 segment battery indicator - Low standby power consumption - Automatic shut down when Battery voltage is lower than 3.1V - Available in QFN20(4X4) Package APPLICATION - Single-chip Power Bank solution - Single-cell lithium-ion / lithium polymer battery charger - Fixed 5V Boost Converter TYPICAL APPLICATION The PM1001 is available in QFN20(4X4) package.
