ISL2111BR4Z-T

Gate Driver Overview

The ISL2111BR4Z-T is a half-bridge gate driver IC manufactured by Renesas Electronics Corporation. It features independent high-side and low-side outputs designed for driving N-channel MOSFETs. The device operates with a supply voltage range of 8V to 14V and supports a maximum bootstrap supply voltage of 114V. Key electrical parameters include a peak pull-up current of 3A and a peak pull-down current of 4A. Typical switching performance includes a rise time of 9ns and a fall time of 7.5ns, with propagation delays of 38ns (turn-on) and 32ns (turn-off). It functions within a temperature range of -40°C to +125°C TJ.

Gate Driver Feature Summary

• Independent high-side and low-side driver channels for half-bridge configurations
• Non-inverting input logic compatible with standard TTL levels
• Robust output stage capable of driving N-channel MOSFETs with high peak currents

Gate Driver Applications

• Half-bridge DC/DC converters
• Full-bridge DC/DC converters
• Two-switch forward converters
• Active-clamp forward converters
• Class-D audio amplifiers

Gate Driver Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required for automated assembly. Confirm the component status as End-of-Life or obsolete through official Renesas notifications prior to finalizing design-in decisions. Ensure compatibility with existing PCB footprints for the 8-DFN package.

Gate Driver Selection Notes

Select this component when a compact half-bridge solution with independent control is required. The 8-DFN package suits space-constrained designs. Verify that the 114V bootstrap rating meets the bus voltage requirements of the target application. Consider thermal dissipation capabilities relative to the expected switching frequency and load conditions.

Gate Driver Part Context

The ISL2111 series belongs to Renesas' portfolio of power management integrated circuits, specifically gate drivers. This model is part of the ISL211x family, which shares similar architectural features but may vary in pin count or packaging options such as SOIC-8 or TDFN-EP-10 variants found in related datasheets.

Gate Driver Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Renesas technical support for qualified alternatives given the product's end-of-life status.
