High performance 100V half-bridge MOSFET drivers

Renesas Electronics has introduced the HIP2211 and HIP2210, a new pair of 100V half-bridge MOSFET drivers.

The HIP2211 is a next-generation pin-compatible upgrade to Renesas’ ISL2111 bridge driver, while the new HIP2210 offers a tri-level PWM input to simplify power supply and motor drive design. The HIP2211 and HIP2210 are intended for 48V telecom power supplies, Class-D audio amplifiers, solar inverters, and UPS inverters.

They have also been designed to be rugged enough to power the demanding 48V motor drives found in Li-ion battery-powered household and outdoor products, water pumps, and cooling fans.

The HIP221x drivers are designed to work reliably under difficult operating conditions, with the high-speed, high-voltage HS pin tolerating up to -10V continuously and slewing as quickly as 50V/ns.

Comprehensive under-voltage protection works in tandem with the HIP2210’s programmable anti-shoot-through protection to ensure the driven MOSFETs are not damaged due to power supply or other external fault conditions.

Renesas’ HIP221x drivers feature strong 3A source, 4A sink drivers with very fast 15ns typical propagation delay and 2ns typical delay matching, making them suitable for high-frequency switching applications. Both the HIP2210 and HIP2211 are designed to complement Renesas microcontrollers in advanced DC/DC and brushless motor drive systems.
