TC78H670FTG

Clock-in and Serial controlled Bipolar Stepping Motor Driver

1. Outline

The TC78H670FTG is a two-phase bipolar stepping motor driver using a PWM

chopper which incorporate DMOS with low on-resistance in output

transistors. The clock-in decoder is built in.

P-VQFN16-0303-0.50-001

Weight: 22.9 mg (typ.)

2. Features

•

Built-in Dual H Bridges, Capable of controlling 1 bipolar stepping motor

PWM controlled constant-current drive

Power supply operating voltage: 2.5 V to 16.0 V

Output current ratings: 2.0 A (max)

Low on-resistance (High + Low side = 0.48 Ω (typ.)) MOSFET output stage

Allows full, half, quarter, 1/8, 1/16, 1/32, 1/64, 1/128 step operation

Built-in Sense resistor less current control architecture (Advanced Current Detection System)

Multi error detect functions (Thermal shutdown (TSD), Over current (ISD), motor load open (OPD)

and Under voltage lockout(UVLO))

•

Error detection (TSD/ISD/OPD) flag output function

Built-in VCC regulator for internal circuit

Chopping frequency of a motor can be adjusted by external resistor

Small QFN package with thermal pad (16pin)

Note: Please be careful about thermal conditions during using.

Note: It is possible to detect OPD only when Serial mode is selected.
