DESCRIPTION
Switch1 Control Input: Logic-compatible, active-low. TTL input
Fault Detection Flag 1 (OUTPUT): Active-low. N-ch open-drain. Indicates over-current,
thermal shutdown, or UVLO conditions
Fault Detection Flag 2 (OUTPUT): Active-low. N-ch open-drain. Indicates over-current,
thermal shutdown, or UVLO conditions
Switch2 Control Input: Logic-compatible, active-low. TTL input
Switch2 Output: Drain of MOSFET for output. Usually, connected to Load
Ground
Power Input: Source of MOSFET for output. Power supply to Internal circuit
Switch1 Output: Drain of MOSFET for output. Usually, connected to Load
