DGD2181M
HIGH-SIDE AND LOW-SIDE GATE DRIVER IN SO-8
Description
Features
The DGD2181M is a high-voltage / high-speed gate driver capable of
driving N-Channel MOSFETs and IGBTs in a half-bridge configuration.
High-voltage processing techniques enable the DGD2181M’s high-side
to switch to 600V in a bootstrap operation.
Floating High-Side Driver in Bootstrap Operation to 600V
Drives Two N-Channel MOSFETs or IGBTs in a Half Bridge
Configuration
1.9A Source / 2.3A Sink Output Current Capability
Outputs Tolerant to Negative Transients
Wide Low-Side Gate Driver and Logic Supply: 10V to 20V
Logic Input (HIN and LIN) 3.3V Capability
Schmitt Triggered Logic Inputs with Internal Pull Down
Undervoltage Lockout for High and Low Side Drivers
Extended Temperature Range: -40°C to +125°C
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
For automotive applications requiring specific change control
(i.e. parts qualified to AEC-Q101, PPAP capable, and
manufactured in IATF 16949 certified facilities), please

The DGD2181M logic inputs are compatible with standard TTL and
CMOS levels (down to 3.3V) for easy interfacing with controlling
devices. The driver outputs feature high-pulse current buffers designed
for minimum driver cross conduction.
The DGD2181M is offered in SO-8 package and the operating
temperature extends from -40°C to +125°C.
