FUNCTION
Control Input for Switch A. The active polarity of ONA is set by SEL (see Table 1).
Power Input. Connect all IN_ inputs together and bypass with a 0.1μF ceramic capacitor to GND. Load
conditions might require additional bulk capacitance to prevent pulling IN_ down.

Control Input for Switch B. The active polarity of ONB is set by SEL (see Table 1).

conditions might require additional bulk capacitance to prevent pulling IN_ down.
Control Input for Switch C. The active polarity of ONC is set by SEL (see Table 1).
Fault Indicator Output for Switch C. Open-drain output asserts low when switch C enters thermal shutdown,
undervoltage lockout, or a sustained (>20ms) current-limit or short-circuit condition.
Power Output for Switch C. Bypass OUTC to GND with a 1μF ceramic capacitor. Load conditions might
require additional bulk capacitance. When disabled, OUTC goes into a high-impedance state.
Logic Input Polarity Select. SEL sets the active polarity of the ON_ inputs. Connect SEL high to set active-
high inputs. Connect SEL to GND to set active-low inputs.
Fault Indicator Output for Switch B. Open-drain output asserts low when switch B enters thermal shutdown,
undervoltage lockout, or enters a sustained (>20ms) current-limit or short-circuit condition.
Power Output for Switch B. Bypass OUTB to GND with a 1μF ceramic capacitor. Load conditions might
require additional bulk capacitance. When disabled, OUTB goes into a high-impedance state.
Ground
Power Output for Switch A. Bypass OUTA to GND with a 1μF ceramic capacitor. Load conditions might
require additional bulk capacitance. When disabled, OUTA goes into a high-impedance state.
Fault Indicator Output for Switch A. Open-drain output asserts low when switch A enters thermal shutdown,
undervoltage lockout, or a sustained (>20ms) current-limit or short-circuit condition.
