IN3-

External Sense Resistor Load-Side Connection for Amplifier 3

17

IN4-

External Sense Resistor Load-Side Connection for Amplifier 4

18

IN4+

External Sense Resistor Power-Side Connection for Amplifier 4. Bias at this pin also provides the supply

voltage for amplifier 4. This pin can be left open circuit if not needed.

19

Supply Voltage for Reference, Comparators, and Logic. A +2.7V to +5.5V supply. This pin should be

decoupled to GND with a 100nF ceramic capacitor.

20

ENA

SHTDN Enable Input. CMOS digital input. Connect to GND to clear the latch and unconditionally

21

SHTDN

Shutdown Output. Open-drain output. This output transitions to high impedance when any of the four

overcurrent comparator outputs (OC1 to OC4) are asserted (high impedance) as long as the ENA pin is

high. Toggling the ENA pin allows SHTDN to reset to logic-low.

EP

Exposed Pad. Connect to ground or leave unconnected.
