CYT101 Datasheet | CYT

.. Voltage and Current Controller Features - - - - - Two ored error amplifiers with built-in current generator with enable/disable function. 1.24V series voltage reference with trimmed 1% tolerance (CYT101A). 4.5 to 32V supply voltage range. 5k V ESD protection. Temperature-pensated. D DIP8 (8-Pin Plastic DIP) DESCRIPTION The CYT101/CYT101A provide a pin-for-pin 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 paring 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 ing from the current sensing resistor. The CYT101/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.

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… + - GND 4 + PIN DESCRIPTION Pin 1 2 Name VREF EN I/O O I Function Trimmed Voltage Reference Output 1.24V, 10m A max. 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 Current Limitation...
