500mA High Voltage Linear Charger with OVP/OCP

一、General Description

YHM2810 is a highly integrated, single-cell Li-ion battery charger with system power path management for space-limited portable applications. The full charger function features Trickle-charge, constant current fast charge and constant voltage regulation, charge termination, and auto recharge.

YHM2810 can deliver up to 500mA charging current, be programmed externally with a single resistor. The charge voltage is default 4.2V and adjustable by Access command. YHM2810 automatically terminates the charge cycle when the charge current drops to 1/20 of the programmed value after the final float voltage is reached. The device can report charging/discharging current for fuel gauging by current monitor output.

Fully Integrated Power Path Switches and no blocking diode is required due to the internal bi-direction MOSFET architecture. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature.

YHM2810 can enter shipping mode by Access command and exit it after input power is present. In shipping mode, battery FET is open and the device only consume 150nA current.

The device status is indicated on STACMD pin output for charging, discharging and charge done. This pin also supports Access command to adjust charging current and charging voltage or enter different mode.

YHM2810 comes in a 2mm x 2mm 8-pin DFN with 0.5 pitch and operates over an ambient temperature range of -40°C to +85°C.

二、YHM2810 Pin Configurations

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended.

In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.

The absolute maximum ratings are stress ratings only.
