Nexperia automotive 120V/4A half-bridge gate driver for robustness and efficiency

Nexperia introduced a new series of high-performance gate driver ICs designed for driving both high-side and low-side N-channel MOSFETs in a synchronous buck or half-bridge configuration. These devices deliver high current output and excellent dynamic performance, boosting efficiency and robustness in applications. The automotive-qualified NGD4300-Q100 is ideal for electronic power steering and power converters, while the NGD4300 has been designed for use with DC-DC converters in consumer devices, servers and telecommunications equipment as well as for micro-inverters used in various industrial applications.
The floating high-side driver in these ICs can operate from bus voltages up to 120 V and use a bootstrap supply with an integrated diode, features which simplify overall system design and help to reduce PCB size. They can deliver up to 4 A (peak) source and 5 A of sink current to guarantee short rise and fall times even for heavy loads. The gate driver has a low 13 ns delay and offers excellent channel-to-channel delay matching of only 1 ns. These delays are significantly lower than for similar competing gate drivers and help to minimize dead-time by maximizing switching duty-cycle. 4 ns rise and 3.5 ns (typical) fall times help to deliver higher efficiency and support high freque...
