HKW-Elektronik GmbH MT 7060-01 / MT 7060-02 Clock Stepping Motor Driver FEATURES Four low resistance output drivers for bipolar or unipolar clock stepping motors Low transversal transition current Very low current consumption: 0.1 µA 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 DESCRIPTION The MT 7060-XX is a 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 (MT 7060-01) which can be connected by metal mask programmation so as to obtain two identical non-inverting circuits with a lower resistance output (MT 7060-02). 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.
