TB67H452FTG
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 bined. 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 k Hz or more
