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.

Supply Voltage VIN .......................... 4.5V to 14V

Driver Voltage VDDDRV..................... 4.5V to 5.5V

Logic Voltage VDD .......................... 4.5V to 5.5V

Operating Junction Temp. (TJ). -40°C to +125°C

Thermal Resistance (4) θJA θJC

6x6mm TQFN......................... 29 ....... 8.... °C/W

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.
