Input 2
Input 1
External reservoir capacitor connection for the internal charge pump;
connected to VPWR. Allowable values are 30 nF to 100 nF. Note: This
capacitor is required for the proper performance of the device.
Logic input control of OUT2;e.g., when IN2 is logic HIGH, OUT2 is set to
VPWR, and when IN2 is logic LOW, OUT2 is set to PGND. (Schmitt trigger
Input with ~ 80 μA source so default condition = OUT2 HIGH.)
Logic input control of OUT1; e.g., when IN1 is logic HIGH, OUT1 is set to
VPWR, and when IN1 is logic LOW, OUT1 is set to PGND. (Schmitt trigger
Input with ~ 80 μA source so default condition = OUT1 HIGH.)

The low-current analog signal ground must be connected to PGND via low-
impedance path (<10 mΩ, 0 Hz to 20 kHz). Exposed TAB is also the main
heatsinking path for the device.
