TB62212FTAG Description
TB62212FTAG TOSHIBA BiCD Process Integrated Circuit Silicon Monolithic TB62212FTAG PWM Chopper Type Dual-Stepping Motor Driver The TB62212FTAG is a PWM chopper type dual-stepping motor driver. Two stepping motor drivers can drive up to four brushed DC motors. Incorporating two pairs of H-bridge drivers, the TB62212FTAG can drive two DC motors or a single stepping motor.
TB62212FTAG Key Features
- Single-chip motor driver for bipolar stepping motor control
- Monolithic IC structured by BiCD process
- Low ON-resistance: Ron = 2.2 Ω (Upper and lower sum of P- and N-channel output transistors: Tj = 25°C @0.6 A typ.) In la
- 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 power supply (5 V) is not required
- Package: Quad leadless package with a backside heat sink (QFN48-P-0707-0.50: 0.5-mm lead pitch)
- Maximum output withstand voltage: 40 V
- Output current: 2.0 A (max) in DC (S) mode; 1.5 A (max) in Stepping (S) mode
- Chopping frequency can be set by external oscillator. High-speed chopping is possible at 100 kHz or higher
