MCP8025/6

3-Phase Brushless DC (BLDC) Motor Gate Driver

with Power Module, Sleep Mode, and LIN Transceiver

Features

Applications

• AEC-Q100 Grade 0 Qualified

• Quiescent Current:

• Automotive Fuel, Water, Ventilation Motors

• Home Appliances

• Permanent Magnet Synchronous Motor (PMSM)

Control

- Sleep Mode: 5 µA Typical

- Standby Mode: < 200 µA

• Hobby Aircraft, Boats, Vehicles

• LIN Transceiver Interface (MCP8025):

- Compliant with LIN Bus Specifications 1.3,

2.2, and SAE J2602

Description

The MCP8025/6 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.

- Supports baud rates up to 20K baud

- Internal pull-up resistor and diode

- Protected against ground shorts

- Protected against loss of ground

- Automatic thermal shutdown

- LIN Bus dominant timeout

• Three Half-Bridge Drivers Configured to Drive

External High-Side NMOS and Low-Side NMOS

MOSFETs:

The MCP8025 device integrates a comparator, a buck

voltage regulator, two LDO regulators, power

monitoring comparators, an overtemperature sensor, a

LIN transceiver, a zero-crossing detector, a neutral

simulator and an operational amplifier for motor current

monitoring. The phase comparator and multiplexer

allow for hardware commutation detection. The neutral

simulator allows commutation detection without a

neutral tap in the motor. The buck converter is capable

of delivering 750 mW of power for powering a

companion microcontroller. The buck regulator may be

disabled if not used. The on-board 5V and 12V

low-dropout voltage regulators are capable of

delivering 30 mA of current.

- Independent input control for high-side

NMOS and low-side NMOS MOSFETs

- Peak output current: 0.5A @ 12V

- Shoot-through protection

- Overcurrent and short-circuit protection

• Adjustable Output Buck Regulator (750 mW)

• Fixed Output Linear Regulators:

5V @ 30 mA

- 12V @ 30 mA

• Operational Amplifiers:

- one in MCP8025

- three in MCP8026

The MCP8026 replaces the LIN transceiver, neutral

simulator and zero-crossing detector in MCP8025 with

two level shifters and two additional op amps.

• Overcurrent Comparator with DAC Reference

• Phase Comparator with Multiplexer (MCP8025)

• Neutral Simulator (MCP8025)

• Level Translators (MCP8026)

• Input Voltage Range: 6V to 40V

• Operational Voltage Range:

- 6V to 19V (MCP8025)

The MCP8025/6 operation is specified over

temperature range of -40°C to +150°C.

Package options include 40-lead 5x5 QFN and 48-lead

7x7 TQFP with Exposed Pad (EP).

- 6V to 28V (MCP8026)

• Buck Regulator Undervoltage Lockout: 4.0V

• Undervoltage Lockout (UVLO): 5.5V (except Buck)

• Overvoltage Lockout (OVLO)

- 20V (MCP8025)

- 32V (MCP8026)

• Transient (100 ms) Voltage Tolerance: 48V

• Extended Temperature Range (T_A): -40 to +150°C

• Thermal Shutdown
