Power Bank PMU Supports Li-Ion Battery Charger
with Integrated Power Path Function and Boost
General Description Features
HE43002 is an integrated Li-ion charger and system Integrated intelligent power path management
(IPPM) function powers the system while charging
power path management device targeted at
the battery
space-limited portable applications. The device
operates from either a USB port or AC adapter and Supports up to charge current with current
supports charge current up to . The input voltage monitoring output
range with input overvoltage protection supports Programmable input current limit up to for wall
unregulated adapters. The USB input current limit adapters
accuracy and start up sequence allow HE43002 to
Programmable pre-charge and fast-charge
meet USB-IF inrush current specification. Additionally,
the input intelligent power management (VIN-IPM) Battery low-power voltage selection by pin
prevents the charger from crashing incorrectly Battery regulation voltage selection by pin
configured USB sources. Reverse current, short-circuit and thermal
protection
HE43002 features intelligent power path management
(IPPM) that powers the system while simultaneously NTC thermistor input
and independently charging the battery. The IPPM Proprietary start up sequence limits inrush current
circuit reduces the charge current when the input
