MOSFET driver delivers automotive voltages

A high-frequency 75V half-bridge N-channel MOSFET driver IC delivers a 2A peak sink and source gate driver current.

A high-frequency 75V half-bridge N-channel MOSFET driver IC delivers a 2A peak sink and source gate driver current.

The new SiP41111 is particularly well suited for automotive applications, which often require voltages up to 40 or 60V.

The 75V MOSFET driver may be used in high-intensity discharge lamps in automobiles, as well as in high-voltage buck convertors, push-pull convertors, full- and half-bridge convertors, active-clamp forward convertors, power supplies, motor control, and class D audio systems in a variety of end products.

The SiP41111 features a maximum bootstrap supply voltage up to 75V, accommodates a broad supply voltage range from 9 to 13.2V, and is capable of driving a 1000pF load with typical rise and fall times of 10ns.

Typical delay match and high-low match times of 6.5ns enable the fast propagation times required for multimegahertz circuits.

An on-chip 1.5ohm bootstrap diode helps to reduce external component count.

Undervoltage protection pushes the outputs to low in the event of an undervoltage event, after which the device turns on again automatically.

The SiP41111 is pin-compatible with the HIP2100 and HIP2101.

Offered in the SOIC-8 and thermally enhanced PowerPAK SOIC packages, samples and production quantities of the SiP41111 are available now, with lead times of 8 to 10 weeks for larger orders.

Pricing for US delivery starts at $0.85 in 1000-piece quantities.
