MIK7060K-XX
Circuit for Low Resistance Output Drivers
for Bipolar or Unpolar
Clock Stepping Motors
June 2001
Description
The MIK7060K-XX is low power integrated circuit in CMOS Silicon Gate technology designed to drive bipolar or unipolar clock stepping
motors. This device contains four identical and independent non-inverting circuits (MIK7060K-01) which can be connected by metal
mask programmation so as to obtain two identical non-inverting circuits with a lower resistance output (MIK7060K-02). Each buffer is
driven by a special cell which dephases the P and N transistor signal input for minimization of the transversal transition current. A tri-
state input HIZ with internal pull-down resistor provides the high impedance state of the four outputs.
Features
Four low resistance output drivers for bipolar or unipolar
clock stepping motors
Low transversal transition current
Very low current consumption: 0.1 mA at 25
C
Two different output resistances programmable by metal
mask
Wide power supply voltage range: 1.1 V to 3.5 V
Tri-state input for applications as fast bus driver
ESD and latch-up protections on input and output pads
Application
Motor driver

Stresses beyond these listed maximum ratings may cause permanent damage to the device. Exposure to conditions beyond specified
operating conditions may affect device reliability or cause malfunction.
Handing Procedures
This device contains circuitry to protect the terminals against damage due to high static voltages or electrical fields. However, it is
advised that normal precautions be taken to avoid application of any voltage higher maximum rated voltages to this circuit.
