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.))

In large mode, ON-resistance of combined H-bridges is: Ron = 1.1 (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.
