R EM MICROELECTRONIC - MARIN SA EM5060 Low Voltage CMOS Driver Circuit Features • • • • • • • Functional Diagram Four low resistance output drivers for bipolar or unipolar watch 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 to 3.5 V. Tristate input for applications as fast bus driver. ESD and latch-up protections on input and output pads.

This device contains four identical and independent noninverting circuits which can be connected by metal mask programation so as to obtain two identical non-inverting circuits with a lower resistance output. Each buffer is driven by a special cell which dephases the P and N transistor signal input, for a minimization of the transversal transition current. A tristate input HIZ, with internal pulldown resistor provides the high impedance state of the four outputs.
