Low Voltage CMOS Driver Circuit
Features
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.
Description
The EM5060 (previously named H5060) is a low power
integrated circuit in HCMOS Silicon Gate Technology
designed to drive bipolar or unipolar stepping motors.
This device contains four identical and independent non-
inverting 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.
Application
Motor driver for watch/clock application
