Description

Product Overview

The TB67H450FNG is a PWM chopper type brushed DC motor driver IC from Toshiba Electronic Devices & Storage Corporation, manufactured using their advanced BiCD process that integrates bipolar, CMOS, and DMOS technologies on a single chip. Rated for 50 V output voltage and 3.5 A peak output current, it provides a compact HSOP8 solution for driving brushed DC motors with high efficiency and robustness. The device supports four operating modes (Forward, Reverse, Brake, Stop/Standby) controlled via two logic input pins, and features both PWM constant current drive and direct PWM drive modes. With low on-resistance of 0.6 Ω (High side + Low side, typical), integrated VCC regulator, and comprehensive protection circuits (thermal shutdown, over-current detection, under-voltage lockout), the TB67H450FNG minimizes external component count and PCB space. The ultra-low standby current of 1 µA maximum makes it particularly suitable for battery-powered and energy-sensitive applications.

The TB67H450FNG is a PWM chopper type brushed DC motor driver IC from Toshiba, fabricated using their proprietary BiCD process integrating bipolar, CMOS, and DMOS technologies. Rated for 50 V output voltage and 3.5 A peak current, it supports four operating modes: forward, reverse, brake, and stop (standby). The device features low on-resistance output MOSFETs (High side + Low side = 0.6 Ω typical) and both PWM constant current drive and direct PWM drive modes. Built-in protection circuits include thermal shutdown (TSD), over-current detection (ISD), and under-voltage lockout (UVLO). With a wide 4.5 V to 44 V operating voltage range and ultra-low standby current of 1 µA maximum, it is ideal for battery-powered devices, home appliances, OA equipment, and industrial applications.

The TB67H450FNG integrates an H-bridge power stage, pre-driver, current sense comparator, PWM control logic, and protection circuits in a single chip. In PWM constant current mode, the motor current is regulated by comparing the voltage across the external current sense resistor (RS pin) with the reference voltage (VREF pin) through a gain of 1/10. When the peak current reaches the set level, the PWM cycle switches to the decay phase. The IN1 and IN2 logic inputs select between four operating modes: forward (IN1=H, IN2=L), reverse (IN1=L, IN2=H), short brake (IN1=H, IN2=H), and stop/standby (IN1=L, IN2=L). In stop mode, both outputs are high-impedance and the IC enters standby mode with minimal power consumption (1 µA typ.). An internal charge pump provides the gate drive voltage for the high-side MOSFETs, and an internal VCC regulator powers the control logic. The BiCD process enables high voltage capability, low on-resistance, and efficient monolithic integration of analog and digital circuits.
