General Purpose Motor Control IC

Oct 5, 2023

1 Description

The RAJ306102 is a general-purpose motor control

2 Features

• Operating power supply voltage:

IC for 3-phase brushless DC (BLDC) motor

- VBRIDGE: 6V to 65V (78V abs max)

- VM: 6V to 60V (65V abs max)

• Operating ambient temperature: -40°C to 105°C

• Supply current:

applications. RAJ306102 combines a smart gate

driver and MCU (RL78/G1F) in a single package.

The smart gate driver includes three half-bridge gate

drivers, a buck switching regulator and a charge

pump for the gate drive voltage, two LDOs for the

internal analog and logic circuitry and MCU, three

accurate differential amplifiers, a BEMF sense

amplifier, three general purpose comparators, and

extensive protection functions.

- MCU, VDD current:

(HS mode, fIH=32MHz: 5.2mA)

- Smart gate driver, VM current:

Operating Mode: 2mA, Sleep Mode: 28μA

• 8mm×8mm 64 Ld QFN package (0.4mm pitch)

Smart Gate Driver function

• 3-Phase drive for BLDC application

The three half-bridge gate drivers are capable of

driving up to three N-channel MOSFET bridges and

support bridge voltages from 6V to 65V. Each gate

driver supports up to 0.64A source and 1.28A sink

peak drive current with adjustable drive strength

control. Adaptive and adjustable dead-times are

implemented to ensure robustness and flexibility.

The active gate holding mechanism prevents miller

effect induced cross-conduction and further

enhances robustness.

- Peak 0.64A/1.28A source/sink current with 16

adjustable drive strength through SPI interface

- Adaptive and adjustable dead time

- 3-phase HI/LI mode and 3-phase PWM mode

- Input control signal configuration

• Fully integrated power supply architecture

- Two 5V LDOs allow for Sleep Mode low IQ

- 500mA buck switching regulator for the gate

drive voltage (5V to 15V adjustable)

- 100mA adjustable output LDO for MCU supplies

• Three differential amplifiers with configurable gain

for current sensing (5, 10, 20, 40V/V)

Three accurate differential amplifiers with adjustable

gain support ground-side shunt current sensing for

each bridge. The device can also support both BLDC

sensor/sensorless motor drive by the three general

purpose comparators or a BEMF sense amplifier.

• BEMF sense amplifier for sensorless motor drive

• Three comparators for hall sensor motor drive

• Extensive protection functions

The protection functions include supply voltage

OV/UV protection, buck regulator OV/UV/OC

protection, charge pump UV protection, MOSFET

VDS OC protection, current sense OC protection,

MOSFET VGS fault, thermal warning, and thermal

shutdown.

MCU (RL78/G1F) function

• CPU: 16bit CISC CPU

• Code flash: 64KB, Data flash: 4KB, RAM: 5.5KB

• Serial array unit: 2 units

(CSI:2ch, UART:1ch, I²C:2ch)

• GPIO: 29 channels: I/O: 27ch, Input: 2ch

• Timer: Timer array unit: 1unit: 16bit, 4ch

- Timer RJ/RG: 16bit, 1ch/1ch

The smart gate driver can be configured to use SPI

interface by the internal connection with MCU. All the

parameters can be set through the SPI interface, and

allows better monitoring. Fault conditions are

reported on the nFAULT signal and each status bit in

the Fault Status registers.

- Timer RD for motor control: 16bit, 2ch

- Timer RX: 16bit, 1ch

• 10-bit resolution A/D converter input: 11ch

• External interrupt input: 10ch

MCU supports H/W of the safe standard of IEC60730

and IEC61508. The development tools of the RL78

family are available.

3 Applications

• Power tools and Garden tools

• Vacuum cleaners, Fans, Pumps, and Robotics
