Pin Description
PIN
NAME
FUNCTION
1
V_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).
