Pin Function
Supply #1 Input: Output MOSFET drain. Also is the supply input for the
common oscillator, thermal shutdown, and flag circuitry. Must be powered to
use switch #2, #3, or #4. Connect to supply for switch #1.
Switch #1 Output: Output MOSFET source. Typically connect to switched
side of load. Output can be pulled above input voltage in off mode.
Control #1 (Input): Noninverting TTL compatible control input.
Ground: Power return.
Control #2 (Input): Same function as CTL1.
Supply #2 Output: Output MOSFET source.
Switch #2 Input: Output MOSFET drain. Also is supply voltage for
respective channel control input and charge pump.
Switch #3 Input: Same function as IN2.
Supply #3 Output: Output MOSFET source.
Control #3 (Input): Same function as CTL1.
Fault Flag (Output): Active-low, open-drain output. If all CTLs are low,
indicates open load. If any CTL is high, indicates current limit or thermal
shutdown.
Control #4 (Input): Same function as CTL1.
Supply #4 Input: Output MOSFET source.
Switch #4 Output: Same function as IN2.
