BD71828GW is a single-chip power management IC for battery-powered portable
|
|
devices. The IC integrates 7 buck converters, 7 LDOs, and a 1500 mA
|
|
single-cell linear charger. Also included is a Coulomb counter, a real-time
|
|
clock (RTC), and a 32.768 kHz clock gate.

BD71827 and BD71828 have SAR ADC for measuring charging currents.
|
|
External sense resistor (RSENSE in data sheet) should be used. If some
|
|
other but 30MOhm resistor is used the resistance value should be given
|
|
here in Ohms.
