Dual half-bridge driver rated for the hot end of digital imaging
The Renesas ISL55110IRZ-T7A is a dual half-bridge power MOSFET driver built for capacitive and resistive loads in digital imaging applications — think piezoelectric actuator drive in printheads or CCD/CMOS sensor timing generators that need fast, high-current gate drive. It delivers a 3.5 A peak output to slam the MOSFET gates open and closed, while the continuous output per channel is rated at 100 mA — the peak figure is what matters for switching speed; the continuous figure sets the steady-state drive budget for the load.
150°C junction — not a standard temp grade
Rated for operation up to 150°C junction temperature.
Active production — no lifecycle contingency needed
No NRND flag, no last-time-buy window on the horizon. The surface-mount QFN footprint is standard for high-density imaging boards.
Rework note: QFN with a critical pad
The 16-QFN (4x4 mm) package has an exposed pad for thermal and electrical ground connection.
