Dear All,
I want to design a low-side bidirectional battery disconnect switch for controlling the battry connection meanwhile its charging/discharging in a BMS.
Is there anyone who could suggest me a circuitry to conroll the connection via a Microcontroller?
Since the power stage of the IGBT`s are based on a BJT structure, it is not usual refer to their Rdson parameters, but rather to their Vceon parameters.
The circuit in post #2 can also be used with power MOSFET's.
IGBT's have a specified voltage drop. Power MOSFET's have a specified resistance.
IGBT's are good for high voltage cricuits. Power MOSFET's are better for low voltage circuits.
Please give specifications/requirements for the "battery disconnect switch".
