TB67H420FTG Key Features
- Supporting large current (9.0 A) and high voltage (50 V) brushed DC motor operation
- Capable of driving two brushed DC motors using dual H-Bridge mode
- Capable of driving one stepping motor using dual H-bridge mode
- Built-in sense resistor less current control. (ACDS: Advanced Current Detection System)
- Low Rds (on) MOSFETs (High side+ Low side=0.33 Ω (typ.))
- Error detection features (Thermal shutdown (TSD), Over current detection (ISD), Power-on-reset (POR)
- Error detection signal output (Error Output)
- Internal VCC (5 V) regulator enables the driver to be operated with a single power supply (VM)
- Adjustable constant current PWM frequency using external ponents
- Small package with thermal pad. (QFN48: 7.0 mm x 7.0 mm)
