ACE4102E

2.5A, 3MHz Switching Charger with Dynamic Power Path Management

VER 1.1

Description

ACE4102E is a switching Li-Ion battery charger with dynamic power-path control and input current

limiting. When a battery is connected, depending on the battery voltage, the DC-DC switching regulator

either pre-conditions, fast-charges the battery or just regulates a system voltage (VSYS) to a preset voltage.

It does not require an external sense resistor for current sensing.

The charging current is determined by

programming ISET1 or ISET2 pin, depending on the state of the USB_DET. If USB_DET is low, indicating

an valid AC adapter input is present, the charge current is set by ISET1; otherwise, it is set by ISET2.

When the battery voltage reaches the termination voltage i.e. 4.2V/4.35V, the charging path disconnects

SYS to BATT. The ACE4102E also includes a dynamic power path when the SYS load current exceeds

current limit of the DCDC regulator internally set, the SYS voltage falls below VBATT, ACE4102E turns on

the power-path to supplement the system load through the batter.
