ISL2111ABZ Renesas 100V Half-Bridge N-Channel MOSFET Driver
The ISL2111ABZ is a high-frequency, 100V half-bridge N-Channel power MOSFET driver IC developed by Renesas Electronics (formerly Intersil), built upon the popular HIP2100/HIP2101 half-bridge driver platform with several significant performance enhancements. Housed in a standard 8-SOIC package with an MSL1 rating and 100% matte tin Pb-free finish, this device is designed to drive two N-Channel MOSFETs in a half-bridge configuration. The ISL2111ABZ features 3.3V/TTL-compatible input thresholds, making it ideal for direct interface with modern microcontrollers and DSPs. Fully RoHS compliant and rated for operation from -40°C to +125°C junction temperature, this driver delivers robust, reliable performance for demanding power conversion applications.
The ISL2111ABZ integrates an on-chip 1W bootstrap diode, eliminating the need for external discrete diodes and reducing BOM cost and board space. Independent inputs for high-side and low-side drivers provide maximum flexibility in control signal routing and timing adjustment. The device incorporates comprehensive protection features including supply undervoltage lockout to prevent driver malfunction under low-voltage conditions, and robust immunity to supply glitches, HS ringing below ground, and HS slewing at high dv/dt rates. The 3A/4A peak output current capability significantly reduces switching power losses and eliminates the need for external totem-pole buffers in most applications.
