TB62212FNG Overview
TOSHIBA BiCD Process Integrated Circuit Silicon Monolithic TB62212FNG TB62212FNG PWM Chopper Type Dual-Stepping Motor Driver The TB62212FNG 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 TB62212FNG can drive two DC motors or a single stepping motor.
TB62212FNG Key Features
- Single-chip motor driver for bipolar stepping motor control
- Monolithic IC structured by BiCD process
- Low ON-resistance: Ron = 2.2 (Upper and lower sum of P- and N-channel output transistors: Tj = 25 @0.6 A (typ.))
- 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: Surface mount package with a backside heat sink: 0.5mm lead pitch)
- Maximum output 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 capacitor. High-speed chopping is possible at 100 kHz or higher
