High-Efficiency Charger

for Li-Ion Batteries

ZSPM4551

Datasheet

Brief Description

The ZSPM4551 is a DC/DC synchronous switching

lithium-ion (Li-Ion) battery charger with fully inte-

grated power switches, internal compensation, and

full fault protection.

Its switching frequency of 1MHz enables the use of

small filter components, resulting in smaller board

space and reduced BOM costs.

In Full-Charge Constant-Current Mode, the regula-

tion is for constant current (CC). Once termination

voltage is reached, the regulator operates in voltage

mode. When the regulator is disabled (the EN pin is

low), the device draws 10µA (typical) quiescent

current.

The ZSPM4551 includes supervisory reporting

through the NFLT (inverted fault) open-drain output

to interface other components in the system. Device

programming is achieved by an I²C™* interface

through the SCL and SDA pins.

Features

•

VBAT reverse-current blocking

Programmable temperature-compensated

termination voltage: 3.94V to 4.18V ± 1%

User programmable maximum charge current:

50mA to 1500mA

Supervisor for VBAT reported at the NFLT pin

Input supply under-voltage lockout

Full protection for over-current, over-temperature,

VBAT over-voltage, and charging timeout

Charge status indication

I C™ program interface with EEPROM registers
