Abstract: A discrete relay driver circuit that includes a first high side gate drive circuit configured to drive a first high side MOSFET and a second high side gate drive circuit configured to drive a second high side MOSFET. The discrete relay driver circuit also includes a first resistor divider configured to sense voltage from the first high side MOSFET, a second resistor divider configured to sense voltage from the second high side MOSFET, and a first low side gate driver circuit configured to drive a first low side MOSFET. The discrete relay driver circuit also includes a second low side gate driver circuit configured to drive a second low side MOSFET based on a first low side enable signal, and a third low side gate driver circuit configured to drive a third low side MOSFET based on a second low side enable signal.
