PIN NAME FUNCTION
1V
DD
Power Input. Bypass V
DD
to GND with a parallel combination of 0.1µF and 1µF ceramic capacitors.
2 BST
Boost Flying Capacitor Connection. Connect a 0.1µF ceramic capacitor between BST and HS for the
high-side MOSFET driver supply.
3 DH High-Side-Gate Driver Output. Driver output for the high-side MOSFET gate.
4 HS Source Connection for High-Side MOSFET. Also serves as a return terminal for the high-side driver.
5 IN_H High-Side Noninverting Logic Input
6 IN_L
Low-Side Noninverting Logic Input (MAX15012A/C and MAX15013A/C). Low-side inverting logic
input (MAX15012B/D and MAX15013B/D).
7 GND Ground. Use GND as a return path to the DL driver output and IN_H/IN_L inputs.
8 DL Low-Side-Gate Driver Output. Drives low-side MOSFET gate.
—EP
Exposed Pad. Internally connected to GND. Externally connect the exposed pad to a large ground
plane to aid in heat dissipation (MAX15012C/D and MAX15013C/D only).
