TC78S122FNG
Features
- Single-chip motor driver for bipolar stepping motor control
HTSSOP48-P-300-0.50 Weight: 0.212 (g)
- Monolithic IC structured by CD process.
- Low ON-resistance: Ron = 0.6 Ω In large mode, ON-resistance of bined H-bridges (Ron) is 0.3 Ω.
- Over-current detection (ISD), thermal shutdown (TSD) and VM power-on reset circuits
- Since the IC incorporates the VCC regulator for internal circuit operation, an external power supply (5 V) is not required.
- Package:HTSSOP48
- Maximum output withstand voltage: 40 V (max)
- Output current: 2.0 A (max) in DC Motor (S) mode; 1.5 A (max) in Stepping Motor (S) mode
- Chopping frequency can be set by external capacitor and resistor. High-speed chopping is possible at 100 k Hz or higher.
