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 50mA 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.

These voltage parameters for reference only, the actual difference because the battery and different
production batches have voltage differences.
The power display will last 4 seconds, then L1 change to flashing, flashing period 2S, pulse width 0.25S, other
LED goes off.
