Half-bridge gate driver with 20ns edges for 5V and 12V rails
The ICL7667CBA+ is a half-bridge gate driver from Analog Devices, designed to drive N-channel MOSFETs in a totem-pole configuration. Two independent drivers with 20ns typical rise and fall times switch the gate charge fast enough to keep cross-conduction losses low in a 100-200 kHz half-bridge — the dead-time budget starts from these edges, not the controller's PWM timer.
Logic thresholds and thermal envelope for the bench
The input logic thresholds — 0.8V VIL and 2V VIH — are TTL-compatible, so a 3.3V or 5V PWM signal from a microcontroller or DSP drives the inputs directly without a level shifter. The inverting input type means the driver output is the complement of the input; pair it with a non-inverting channel on the same die for a push-pull pair. Operating junction temperature spans 0°C to 150°C, covering industrial ambient conditions with margin for self-heating at high switching frequencies.
Active production, ROHS3, and sourcing posture
The 8-SOIC (0.154-inch body width, 3.90mm) footprint is standard across the industry, so second-source gate drivers from other vendors with the same pinout and supply range can be evaluated for BOM risk mitigation. No official pin-compatible cross-reference is published by Analog Devices for this order code.
