BD71815AGW

General Description



Battery Monitoring and Alarm Output

-Under Voltage Alarm while discharging

-Over Current Alarm

-Over/Under Temperature Alarm

-Programmable thresholds and time durations

Real Time Clock with 32.768kHz crystal oscillator

-32.768kHz clock output

BD71815AGW is a single-chip power management IC

for battery-powered portable devices. The IC integrates

5 buck converters, 8 LDOs, a boost driver for LED, and

a 500mA single-cell linear charger. Also included is a

Coulomb counter, a real-time clock (RTC), a 32 kHz

crystal oscillator and a general-purpose output (GPO).

(Open Drain or CMOS Output Selectable)

1 GPO (Open Drain or CMOS Output Selectable)

Power Control I/O

The IC’s buck converters supply power to the application

processor as well as system peripherals such as DDR

memory, wireless modules, and touch controllers. These

regulators maintain high efficiency over a wide range of

current loads by supporting both PFM and PWM modes.

They also operate at a high switching frequency of

6MHz, which allows the use of smaller and cheaper

inductors and capacitors. The regulator supplying the

processor core also supports Dynamic Voltage Scaling

(DVS).
