DESCRIPTION
The MP86885 is a monolithic half-bridge with
built-in internal power MOSFETs and gate
drivers. It achieves 40A 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 MP86885 is a Monolithic IC approach to
drive up to 40A per phase. This very small 4mm
x 6mm FC-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 MP86885 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 T
J
(MAX), the junction-to-
ambient thermal resistance θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T

)/θ
JA
. Exceeding the maximum allowable powe
r
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
