onsemi FAN8811T High Side and Low Side Gate Driver IC
onsemi FAN8811T High Side and Low Side Gate Driver IC is a high side and low side gate-drive IC designed for high-voltage, high-speed, driving MOSFETs operating up to 100V. The FAN8811 integrates a driver IC and a bootstrap diode. The onsemi FAN8811T featured low delay time and matched PWM input propagation delays, which further enhanced the performance of the part. The high-speed dual gate driver is designed to drive both the high-side and low-side N-Channel MOSFETs in a half-bridge or synchronous buck configuration.
