Toshiba Electronics Europe TC78H660FTG/TC78H660FNG

The TC78H660FTG/FNG is housed in a QFN16/TSSOP16 package with a widely used pin-assignment. It is based on Toshiba's latest generation DMOS process and can deliver a PWM-controlled maximum current of 2 A. Running off a 2.5 to 16 V input supply voltage, it can drive two brushed DC motors or a single stepper motor.

The ON-resistance of this driver at typical operating conditions is just 0.48 Ω. This is highly advantageous from a thermal management perspective, as there is considerably less heat that needs to be dissipated - thereby leading to system cost and space savings.

Key features

• Advanced Current Detection System (ACDS)
• Ultra-low standby current conserves battery power
• Low ON-resistance reduces generated heat
• Compact package for space-constrained applications

Additional features

• Built-in dual H-Bridge
• ACDS eliminates the need for costly and bulky shunt resistors on the PCB
• Output current rating: 2A (max.)
• Ultra-low standby current:
  • 0.1 µA (max.) at Ta = 25 °C
• Low ON-resistance MOSFET output stage:
  • High + Low side = 0.48 Ω (typ.)
• Multiple error detecting functions:
  • Thermal shutdown (TSD)
  • Overcurrent (ISD)
  • Undervoltage lockout(UVLO)
• Error detection (TSD/ISD) flag output function
• Built-in VCC regulator for the internal circuit
• The chopping frequency of a motor can be adjusted by an external resistor
• Selectable CW/CCW/Stop/Brake modes
• Compact package for space-constrained applications:
  • QFN16 with a thermal pad (TC78H660FTG)
  • TSSOP16 (TC78H660FNG)

Additional Benefits
