LV8773 - PWM Constant-Current Control Stepping Motor Driver

Description

of operation (1) Chip enable function This IC is switched between standby and operating mode by setting the ST pin.

In standby mode, the IC is set to power-save mode and all logic is reset.

In addition, the internal regulator circuit and charge pump circuit do not operate in standby mode.

Features

  • BiCDMOS process IC.
  • Low on resistance (upper side : 0.3Ω ; lower side : 0.25Ω ; total of upper and lower : 0.55Ω ; Ta = 25°C, IO = 2A).
  • Motor current selectable in two steps.
  • Output short-circuit protection circuit (selectable from latch-type or auto-reset-type) incorporated.
  • Unusual condition warning output pins.
  • No control power supply required Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Supply voltage Output peak curre.
