Power and Ground CP1 1 IO Charge-pump flying capacitor Connect a 0.01- μF 100-V capacitor between CP1 and CP2. CP2 2 IO Charge-pump flying capacitor 12, 20, 28, GND – Device ground Connect to system ground PPAD Bypass to GND with a 0.47- μF 6.3-V ceramic capacitor. Use V3P3OUT 15 O 3.3-V regulator output for suppling external loads is permissible. VCP 3 IO High-side gate drive voltage Connect a 0.1- μF 16-V ceramic capacitor to VM. Connect to power supply (8.2 V–60 V). Connect both pins to VM 4, 11 – Main power supply the same supply. Bypass to GND with a 10-µF (minimum) capacitor. Control EN1 26 I Channel 1 enable Logic high enables OUT1. Internal pulldown EN2 24 I Channel 2 enable Logic high enables OUT2. Internal pulldown EN3 22 I Channel 3 enable Logic high enables OUT3. Internal pulldown IN1 27 I Channel 1 input Logic input controls state of OUT1. Internal pulldown IN2 25 I Channel 2 input Logic input controls state of OUT2. Internal pulldown IN3 23 I Channel 3 input Logic input controls state of OUT3. Internal pulldown Active-low reset input initializes internal logic and disables the nRESET 16 I Reset input outputs. Internal pulldown Logic high to enable device, logic low to enter low-power sleep nSLEEP 17 I Sleep-mode input mode. Internal pulldown Status Logic low when in fault condition (overtemperature, nFAULT 18 OD Fault overcurrent, UVLO) Comparator COMPN 13 I Comparator negative input Negative input of comparator COMPP 12 I Comparator positive input Positive input of comparator nCOMPO 19 OD Comparator out Output of comparator.
