1EDN7136G

概要

EiceDRIVER™ 200 V high-side TDI gate driver IC for GaN SG HEMTs and MOSFETs

The EiceDRIVER™ 1EDN7136G is a single-channel gate-driver IC optimized for driving Infineon CoolGaN™ Schottky gate (SG) HEMTs, as well as other GaN SG HEMTs and Si MOSFETs. This gate driver includes several key features that enable a high-performance system design with fast-switching transistors, including Truly Differential Input (TDI), 1 A peak source and sink current, active Miller clamp, adjustable charge pump, and bootstrap voltage clamp. Thanks to the TDI feature, the gate driver output state is exclusively controlled by the voltage difference between the two inputs, independent of the driver’s reference (ground) potential as long as the common-mode voltage is below 150 V (static) and 200 V (dynamic). This eliminates the risk of false triggering due to ground bounce in low-side applications, while also allowing 1EDN7136G to address even high-side applications.

特長

Fully differential logic input circuitry to avoid false triggering in low-side or high-side operation
High common-mode input voltage range (CMR) up to ± 200 V for high side operation
High immunity to common-mode slew rate (100 V/ns) for robust operation during fast switching transients
Compatible with 3.3 V or 5 V input logic
1 A source/sink current capability
Active Miller clamp with 5 A sink capability to avoid induced turn-on
Optional negative charge pump provides additional induced turn-on immunity when needed
Active bootstrap clamping
Suitable for driving GaN HEMTs or Si MOSFETs
Qualified according to JEDEC for target applications

利点

High side driving and low side ground bounce immunity during fast switching transitions
Optimized switching speed without external gate resistors, by choosing from the family of 1EDN71x6x drivers
Induced turn-on immunity during fast switching transitions
Regulated bootstrap voltage, by eliminating bootstrap capacitor overcharging during dead-time
