The ISL73041SEH is a Radiation Hardened PWM

input 12V Half Bridge GaN FET Driver designed to

drive low rDS(ON) Gallium Nitride FETs for DC/DC

switching regulators. An integrated programmable

GaN FET gate drive voltage, high-side bootstrap

switch, and strong gate drive current provide a

compact and robust GaN FET half-bridge driver.

The ISL73041SEH can interface directly to the

ISL73847SEH dual-phase PWM buck controller to

create a high-efficiency point-of-load regulator to

power many of the latest low voltage high current

FPGA and DSP digital core rails.

Applications

▪ High current DC/DC Point-of-Load (POL) for FPGA

and DSP supply rails

▪ 5V or 12V input to 1V output POL regulation

▪ GaN FET motor driver

▪ Combine with ISL73847SEH DC/DC PWM

controller and Renesas GaN FETs for a complete

DC/DC solution

Features

▪ Qualified to Renesas Rad Hard QML-V Equivalent

Screening and QCI Flow (R34TB0001EU)

• All screening and QCI is in accordance with

MIL-PRF-38535L Class-V

▪ Up to 20V bootstrap voltage half-bridge driver

▪ Programmable 4.5V to 5.5V gate drive voltage

▪ Single tri-level PWM input control

▪ Separate source and sink driver outputs

▪ High-side peak drive: 2A Sourcing, 4A Sinking

▪ Low-side peak drive: 4A Sourcing, 8A Sinking

▪ High and low side programmable dead time control

▪ Highly matched fast propagation delay: 29ns

▪ Full military temperature operation TA = -55°C to

125°C ambient range

▪ TID Rad Hard Assurance (RHA) testing

•LDR (≤ 10mrad(Si)/s): 75krad(Si)

▪ SEE Characterization (see SEE report for details)

• No DSEE with VDD = 20V or PHS = 13.5V at

LET 86MeV·cm2/mg

• No DSEE with VDD = 20V or PHS = 16.5V at

LET 67MeV·cm2/mg

• SEFI <10µm2 at 86MeV·cm2/mg

• No Half-Bridge Shoot-Through SET at LET

86MeV·cm2/mg
