H-bridge motor driver TB67H452FTG

for DC motors

The TB67H452FTG is a PWM chopper type 4 ch H-bridge motor driver. The TB67H452FTG can drive two steppers, two DC brushed motors and one stepping motor, etc. by combining 4 ch H-bridges. And it can also drive dual DC brushed motors or stepping motors for large-current drive by setting Large mode. Moreover, VM power supply voltage can be used 6.3 V or more. Therefore, it is optimal for battery powered applications with 7.2 V power supply for example. Features ● Single-chip brushed DC motor driver for up to 4 motors ● Single-chip bipolar stepping motor driver for up to 2 motors ● Monolithic IC structured by CD process ● Low ON-resistance: Ron = 0.6 Ω In Large mode, H-bridges can be combined. ON-resistance (Ron) = 0.3 Ω. ● Over-current detection (ISD), thermal shutdown (TSD), and VM power-on reset circuits ● Since the IC incorporates a VCC regulator for internal circuit operation, an external logic power supply (5 V) is not required ● Package: QFN48 ● Maximum output withstand voltage: 40 V (max) ● Output current: 3.5 A (peak) in DC Motor (S) mode ● Chopping frequency can be set by external capacitor and resistor High-speed chopping is possible at 100 kHz or more
