IR2085STR Description

Short technical summary and product information.

The Infineon Technologies IR2085STR is a high-speed, self-oscillating half-bridge driver IC with a 50% duty cycle. It is suitable for 36V-75V half-bridge DC-bus converters and push-pull converters. This IC integrates an oscillator and half-bridge driver into a single SO-8 package, reducing component count and board space.

 

Key electrical specifications include a maximum switching frequency of 500kHz, +/- 1A drive current capability, and adjustable dead-time ranging from 50ns to 200ns. The floating channel is designed for bootstrap operation up to +100Vdc, with high and low side pulse width matching to +/- 25ns. The device operates with a supply voltage range of 10V to 15V and a high-side voltage of 100V.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, the IR2085STR is designed for efficient power management solutions. Its operating temperature range is -40°C to 150°C (TJ). The device features independent channels and N-Channel MOSFET gate type, with an RC input circuit.

 

This gate driver is ideal for applications requiring efficient power conversion and control in distributed systems, particularly those operating at 48V. Its integrated features simplify design and enhance performance in demanding power supply applications.
