FEATURES
Two ored error amplifiers with built-in current
generator with enable/disable function.
1.24V series voltage reference with trimmed 1%
tolerance (
CYT
101A).
4.5 to 32V supply voltage range.
5kV ESD protection.
Temperature-compensated.
DESCRIPTION
The
CYT
101/
CYT
101A
replacement of TSM101/A. This is an 8-pin voltage
& current controller incorporates a trimmed series
bandgap voltage reference, two ored error amplifiers
and a current source.
This IC provides a feedback to the primary side of a
power supply by comparing the DC voltage and the
current level at the output to an internal reference.
The controlled current generator can be used to
modify the level of current limitation by offsetting the
information coming from the current sensing
resistor.
The
CYT
101/A can be used in every types of
application requiring a precision voltage regulation
and current limitation. For example, designers can
save space by using this 8-pin IC for a CC/CV mode
battery charger.
APPLICATIONS
This circuit is designed to be used in battery
chargers with a constant voltage and a limited
output current.
It can be used in every types of application requiring
a precision voltage regulation and current limitation.
Other application include voltage supervisors, over
voltage protection…

Current source enable input. This current source can be used to
Offset the voltage measurement on the sense resistor and therefore to modify
the charge current. The current source is enabled when the
Input voltage on pin 2 is lower than 0.8V
