● Single-chip motor driver for bipolar stepping motor control
● Monolithic IC structured by BiCD process.
● Low ON-resistance: Ron = 2.2 Ω
(Upper and lower sum of P- and N-channel output transistors: Tj = 25 °C@0.6 A (typ.))
In large mode, ON-resistance of combined H-bridges is: Ron = 1.1 Ω (Upper and lower sum of P and N channel output
transistors: Tj = 25 °C @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.
