Toshiba Bi-CMOS Linear Integrated Circuits

Toshiba Bi-CMOS Linear Integrated Circuits are used in brushed DC motor applications and feature two output driver channels each. The Toshiba Bi-CMOS circuits enable direct drive of motors with efficiency and have a low on-resistance and PWM control. The ICs provide highly efficient motor drive outputs, ensuring optimal performance.

Features

Motor driver block
Dual-channel, H-bridge driver
(R_ON(Nch+Nch)) < 350mΩ (Max @ T_j = 150°C, V_BAT = 8V)
Dual-channel mode and combined-channel mode selectable, connecting two outputs externally allows this IC to function as a single-channel H-bridge circuit, and the device is also used as a 4-channel Half Bridge driver
Detection features
- Over-current detection, over-temperature detection, V_BAT under-voltage detection, and V_CC under-voltage detection
Initial diagnosis
- Power supply fault detection circuit (V_BAT under-voltage and V_CC under-voltage)
PWM control output
Forward/reverse/brake modes
Current limit control
- Chopper-type current limiter
High-side output current monitoring function (CM1 and CM2 pins)
Open-load detection
- During operation/non-operation

DIAG output (DIAG1 and DIAG2 pins)
H-bridge mode/half-bridge mode selectable (OSEL1 and OSEL2 pins)
Low-power Sleep Mode
Through-current prevention circuit
AEC-Q100/AEC-Q006 Capable
SPI communication
- Fault reporting, device settings, and motor control through the SPI registers
Operating voltage range
- V_BAT = 4.5V to 28V (absolute rating of power supply voltage = 40V (max.) (0.5s))
- V_CC = 4.5V to 5.5V
- V_DDIO = 3.0V to 5.5V
Operating temperature range
