BQ2002 NiMH Charging Circuit not working


Thank goodness your circuit does not work. Did you read the datasheet for the BQ2002?

The datasheet clearly shows how to connect the controller:




You have no connection from Bat to the NiMH you are charging ....so no voltage sensing.
You have no current limiting or detection in the charge path, so no way to control the charging current.
You give no idea of the cell/pack voltage, but the circuit you show would only work for 1 or 2 cells since the diode drop would be close to 1V and the TIP32C saturation voltage is over 1V.
