Description
The RRP68151 is a 5V‑powered, high‑frequency half‑bridge driver optimized for enhancement‑mode GaN FETs and low‑threshold N‑channel MOSFETs. It delivers 2A source and 5.3A sink current capability, supporting a switching node up to 100V DC. The driver’s PWM inputs are compatible with 3.3V/5V CMOS logic and can tolerate up to 14V, independent of the VDD supply. The high‑side bias voltage uses a bootstrap technique and is internally clamped at 5.4V to prevent exceeding the GaN FET’s maximum gate‑source rating. A 5V operational supply simplifies power sharing with the controller.
As part of the RRP6815x driver family, the RRP68151 maintains consistent design and performance across related products. Unlike the RRP68150, it does not include integrated anti‑shoot‑through protection, allowing designers to implement their own external timing or protection scheme as needed.
