BIDIRECTIONAL PRECISION
HIGH-SIDE CURRENT
MONITOR
DESCRIPTION
The UTC UCM101 is a bidirectional precision high-side current
sense monitor. It uses UTC’s advanced technology to provide
customers with a minimum operating current, high accuracy, high
side voltage and a fixed gain of 10, etc.
The UTC UCM101’s output voltage is proportional to the
differential input voltage. Direction of current flow is indicated by
the Flag pin.
The UTC UCM101 is suitable for widely voltage range
applications and portable battery equipment.

APPLICATION INFORMATION
A common application for micro-power current monitors is measuring the discharge current of a rechargeable
lithium ion/polymer battery. The UTC UCM101 enables measuring both the charge and discharge current into the
battery and with its wide operating voltage of 2.5~20V enables it to measure the currents in to/ out of up to 4 cells
connected in series.
When choosing appropriate values for RSENSE a compromise must be reached between in-line signal loss
(including potential power dissipation effects) and small signal accuracy.
Higher values for RSENSE gives better accuracy at low load currents by reducing the inaccuracies due to internal
offsets. For best operation the UTC UCM101 has been designed to operate with VSENSE of the order of
50mV~150mV.
