Wide 4.5V to 21V Operating Input Range
20A Output Current
Simple Logic Interface(5.0V)
Operate from 100kHz to 1MHz
Accepts 3-state PWM Input
Suitable for single-/multi-phase operation
Available in a 5mm x 5mm QFN Package
ROHS6 Compliant
Integrating the Driver and MOSFETs results in
high efficiency due to optimal dead time control
and parasitic inductance reduction.
The MP86961 is a Monolithic IC designed to
drive up to 20A per phase. Housed in a very
small 5x5mm QFN Packge, this device can be
operated from 100kHz to 1MHz.
