Wide 4.5V to 14V Operating Input Range
Simple Logic Interface
55A Output Current
Accepts Tri-State PWM Signal
Built-In Switch for bootstrap
Current Sense
Temperature Sense
Current Limit Protection
Used for Multi-Phase Operation
Available in 6mm x 6mm TQFN Package
ROHS6 Compliant
Integration of the driver and MOSFETS results
in high efficiency due to optimal dead time
control and parasitic inductance reduction.
The MP86884 is a Monolithic IC approach to
drive up to 55A per phase. This very small
6mmx6mm TQFN device can operate from
100kHz to 1MHz.
APPLICATIONS
This device works with tri-state output
controllers. It also comes with a general-
purpose current sense and temperature sense.
