Part Number:BQ24261
ESD testing causes device to stop charging. Charge current drops from ~400 mA to ~100 mA and charger status reads "READY". Can read battery voltage before and after ESD event over I2C, so believe device is not completely locked up. Have tried disconnecting/reconnecting the input source voltage (12V) with battery connected, disconnecting/reconnecting battery with input voltage still connected, toggling the Hi-Z (CD pin) with battery and input voltage connected, and toggling the charger enable (CE) bit through the I2C. None of these efforts have caused the device to begin charging, device remains in the "READY" state with no errors reported. Only disconnecting/reconnecting the battery AND the input voltage causes the battery charger to begin working. Is there a way to restart the device assuming it is not in a latched up state?
Yes, this device is not recommended for new designs, but this is an old design that is currently in production and has shown signs of being susceptible to ESD. Any thoughts on how to get the device back up and running?
