MP86884
Intelli-PhaseTM Solution (Integrated
HS/LS FETs and Driver) in 6x6mm TQFN
DESCRIPTION
The MP86884 is a monolithic half-bridge with
built-in internal power MOSFETs and gate
drivers. It achieves 55A of continuous output
current over a wide input supply range.
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.
This device works with tri-state output
controllers. It also comes with a general-
purpose current sense and temperature sense.
The MP86884 is ideal for server applications
where efficiency and small size are a premium.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation will cause excessive die temperature.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
