STK672-732AN-E
Stepper Motor Driver IPM
(Intelligent Power Module)
Unipolar 2-Phase
Overview
The STK672-732AN-E is a IPM for use as a unipolar,
2-phase stepper
motor driver with PWM current control.
Applications
Office photocopiers, printers, etc.
Features
Built-in overcurrent detection function, overheat detection function (output
current OFF).
FAULT signal (active low) is output when overcurrent or overheat is detected.
Built-in power on reset function.
Phase signal input driver activated with an active Low and incorpororates a
simulataneous ON prevention function.
Supports schmitt input for 2.5 V high level input.
Incorporating a current detection resistor (0.141 : resistor tolerance 2%),
motor current can be set using two external resistors.
The ENABLE pin can be used to cut output current while maintaining the
excitation mode.
Supports compatible pins with STK672-740AN-E.

Notes
*1: A fixed-voltage power supply must be used.
*2: The value for Ioave assumes that the lead frame of the product is soldered to the mounting circuit board.
Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond the Recommended
Operating Ranges limits may affect device reliability.
Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product performance may not be
indicated by the Electrical Characteristics if operated under different conditions.

Notes
The current range given above represents conditions when output voltage is not in the avalanche state.
If the output voltage is in the avalanche state, see the allowable avalanche energy for STK672-7** series IPMs given in
a separate document.
The operating substrate temperature, Tc, given above is measured while the motor is operating.
Because Tc varies depending on the ambient temperature, Ta, the value of I
OH
, and the continuous or intermittent
operation of I
OH
, always verify this value using an actual set.
The Tc temperature should be checked in the center of the metal surface of the product package.
