Working Principle

The BTS432E2NKSA1 works as an isolator and can be used as a DC load switch, as a pulse width modulator, or as a PWM switch. It is capable of driving a single MOSFET or a dual MOSFET as a back-to-back switch. The input consists of two inputs, one for the control signal and the other for the enable signal. When the enable signal is high, the device is enabled and the output is turned on. When the control signal is low, the output is turned off.The BTS432E2NKSA1 also features an adjustable dead time, adjustable gate drive current, and adjustable input signal threshold. These features allow the device to be used in a variety of applications.

The BTS432E2NKSA1 also features a hot-swap capability, which allows the device to be enabled or disabled while the power is still applied. This feature is particularly useful for applications like motor control, where it is necessary to have the power switch off while the motor is stopped. Additionally, the device features an open drain output pin, which can be used to adjust the pull-up or pull-down resistance of the device.
