Source of high-side MOSFET1 and drain of low-side MOSFET1.
When
input with ~80 µA sink so default condition = disabled.)
High-current power ground pins must be connected together physically as
close as possible and directly soldered down to a wide, thick, low resistance
ground plane on the PCB.
Open drain active LOW Status Flag output (requires an external pullup resistor
to V
< 0.4 V
When D1 is logic HIGH, both OUT1 and OUT2 are tri-stated. Schmitt trigger
input with ~80 µA source so default condition = disabled.
Source of high-side MOSFET2 and drain of low-side MOSFET2.
External reservoir capacitor connection for internal charge pump; connected to
VPWR. Allowable values are 30 νF to 100 νF. Note This capacitor is required
for the proper performance of the device.
