DESCRIPTION

The MP86952 is a radiation-tolerant, monolithic

half-bridge IC with built-in internal power

MOSFETs and gate drivers. It achieves up to

70A of continuous output current across a wide

3V to 16V input voltage range.

This Intelli-Phase? solution can drive up to

70A of current per phase. The integrated

MOSFETs and drivers achieve high efficiency

through optimized dead time (DT) and reduced

parasitic inductance. The MP86952 has an

operating range of 100kHz to 3MHz.

This device offers many features to simplify

system design. It is compatible with tri-state

pulse-width modulation (PWM) signal

controllers, has Accu-SenseTM current sense to

monitor the inductor current (IL), and has

temperature sense to report the junction

temperature (TJ).

The MP86952 is ideal for server applications

where efficiency and small size are critical. The

MP86952 is available in an LGA-41 (5mmx6mm)

package.
