ZHCSVT2A April 2022 – April 2024 BQ76922
PRODUCTION DATA
The BQ76922 device contains an integrated 1.8V LDO (REG18) that provides a regulated 1.8V supply voltage for the device's internal circuitry and digital logic. This regulator uses an external capacitor connected to the REG18 pin, and it should only be used for internal circuitry.
The device also integrates a programmable LDO (REG1) for external circuitry, such as a host processor or external transceiver circuitry. The REG1 LDO takes its input from the REGIN pin, with this voltage either provided externally or generated by an on-chip preregulator (referred to as REG0). The REG1 LDO can provide an output current of up to 45mA.
