Renesas HIP2211 and HIP2210 half-bridge MOSFET drivers

Renesas Electronics has introduced the HIP2211 and HIP2210 — a pair of 100 V half-bridge MOSFET drivers. The HIP2211 is a next-generation pin-compatible upgrade to the company’s ISL2111 bridge driver, while the HIP2210 offers a tri-level PWM input to simplify power supply and motor drive design.

The HIP221x drivers are suitable for 48 V telecom power supplies, Class-D audio amplifiers, solar inverters and UPS inverters. They are also rugged enough to power the demanding 48 V motor drives found in Li-ion battery-powered household and outdoor products, water pumps and cooling fans.

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

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