Description
The bq76200 device is a low-power, high-side, N-channel system. A high-side protection avoids ground disconnection in the system and also allows continuous communication between the battery pack and host system. The device has additional P-Channel FET control to allow low-current pre-charge to a deeply depleted battery, and a PACK+ voltage monitor control for the host to sense the PACK+ voltage. The independent enable inputs allow CHG and DSG FETs to be turned on and off separately, offering great implementation flexibility in battery systems. The bq76200 device can be used with a companion analog front end (AFE) device such as the bq76920/30/40 family, a 3-series to 15-series Cell Analog Front End Monitoring, and a host microcontroller or dedicated state-of-charge (SOC) tracking gas gauge device.

DESCRIPTIONTop of battery stack Gate drive for charge FET Charge FET enable Charge pump enable (internally logic OR'ed with CHG_EN and DSG_EN signals) Gate drive for discharge FET Discharge FET enable No connect. Leave the pin floating Analog input from PACK+ terminal PACK voltage after internal switch (Connect to MCU ADC via resistor divider.) Gate drive for precharge FET Precharge FET enable Pack monitor enable (allows connection of internal switch between PACK and PACKDIV) Charge pump output. Connect a capacitor to BAT pin. Do not load this pin. Ground reference
P = Power Connection, O = Digital Output, AI = Analog Input, I = Digital Input, I/OD = Digital Input/Output (2) Leave the pin float if the function is not used. It is recommended to connect the pin to ground if the function is not used.
