Description

The MCP8021/2 devices are 3-phase Brushless DC

(BLDC) power modules containing three integrated

half-bridge drivers, capable of driving three external

NMOS/NMOS transistor pairs. The three half-bridge

drivers are capable of delivering a peak output current

of 0.5A at 12V for driving high-side and low-side

NMOS MOSFET transistors. The drivers have shoot-

through, overcurrent and short-circuit protection. A

Sleep mode has been added to achieve a typical “key

off” quiescent current of 5 µA.

The MCP8021/2 devices integrate a 3.3V or 5.0V

LDO regulator for host and peripheral power, an

overtemperature sensor and user-configurable functions.

The user-configurable functions are: dead time, blank-

ing time, op amp enable/disable during standby, enable/

disable Sleep mode, enable/disable overcurrent

detection and enable/disable gate drive undervoltage

protection.

The on-board 3.3V or 5.0V dropout voltage regulators

are capable of delivering 70 mA of current. The

voltage option is selected by part number.

The MCP8022 device adds three independent

operational amplifiers for general use.

The MCP8021/2 functional operation is specified over

a junction temperature range of -40°C to +165°C.

Package options for the MCP8021 include 28-Lead

5x5 mm VQFN and 28-Lead TSSOP-EP. Package

options for the MCP8022 include 40-Lead 5x5 mm

VQFN and 38-Lead TSSOP-EP.
