Product Description

The Micrel MIC4605 is an 85V half-bridge MOSFET driver that features adaptive-dead-time and shoot-through protection.
The adaptive-dead-time circuitry actively monitors the half-bridge outputs to minimise the time between high-side and low-side MOSFET transitions thereby maximising power efficiency. Anti-shoot-through circuitry prevents erroneous inputs and noise from turning both MOSFETS on at the same time.

The MIC4605 also offers a wide 5.5V to 16V operating supply range to maximize system efficiency. The low 5.5V operating voltage allows longer run times in battery-powered applications. An internal high-voltage Schottky diode charges the high-side gate-drive bootstrap (external) capacitor. Additionally the MIC4605's adjustable gate drive sets the gate drive voltage to VDD for optimal MOSFET RDS(ON) which minimises power loss due to the MOSFET's RDS(ON).
The MIC4605 is available in an 8-pin SOIC package and a tiny 10-pin 2.5mm x 2.5mm TDFN package. Both packages have an operating junction temperature range of -40°C to +125°C.
