ISL9519C - Narrow VDC Regulator/Charger
PIN NUMBER 1 2 3 5 SYMBOL VSMB RST# ACOK BGATE DESCRIPTION SMBus interface Supply Voltage Input.
Bypass with a 0.1µF capacitor to AGND.
Logic input sets all SMBus registers to default values when low.
AC Detect Output.
This open drain output is high impedance when ADET is greater than 3.2V.

Narrow VDC Regulator/Charger with SMBus Interface and Internal Switching FETs ISL9519C The ISL9519C is a highly integrated Narrow VDC system voltage regulator and battery charger controller.
Operating parameters are programmable over the System Management Bus (SMBus).
The ISL9519C is designed for applications where the system power source is either the battery pack or the output of the regulator/charger.
This makes the max voltage to the system equal to the max battery voltage instead of the max
