100V, 3A Source, 4A Sink, High Frequency Half-Bridge Driver with Tri-Level PWM Input & Adjustable Dead Time

The RRP68145 is a 100V, 3A source, 4A sink high-frequency half-bridge MOSFET driver. The RRP68145 features a tri-level PWM input with programmable dead time. Its wide operating supply range of 6V to 18V and integrated high-side bootstrap diode supports driving the high-side and low-side NMOS in 100V half-bridge applications.

The RRP68145 features strong 3A source, 4A sink drivers with very fast 30ns typical propagation delay, making it optimal for high-frequency switching applications. VDD and boot UVLO protect against an undervoltage operation.

The tri-level input of the pulse-width modulation (PWM) pin controls the high-side and low-side drivers with a single pin. When the PWM input is at logic high, the high-side bridge FET is turned on and the low-side FET is off. When the input voltage is in the mid-level state, both the high-side and low-side bridge FETs are turned off. The PWM threshold levels are proportional to an external input reference voltage on the REF input voltage range (VREF) pin, allowing PWM operation across a 2.7V to 5.5V logic range.

The RRP68145 is offered in a 16 Ld 3mm x 3mm QFN package.
