MP26085 CC/CV Controller The Future of Analog IC Technology DESCRIPTION FEATURES Constant Voltage and Constant Current The MP26085 is a voltage and current control IC Control integrated a precision voltage reference and a 1.223V built-in voltage reference with 1% current source, which is suitable for battery Accuracy charger, second controller of switching regulator Wide input voltage range: 7V to 20V systems, and other types of application required an accurate voltage and current control systems. Two Operational Amplifier with ORED Output and 1MHz bandwidth This IC compares the DC voltage and the current Built-in Current Generator with level at the output of a switching power supply to Enable/Disable Function the voltage reference and current limitation, 8-Pin TSOT23 Package respectively. It provides a feedback through an opto-coupler to the PWM controller IC at the APPLICATIONS primary side. Battery Chargers The current source is controlled externally, which Every Types of Application Required an can be used to modify the level of current Accurate Voltage and Current Control limitation by offsetting the information coming All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. from the current sensing resistor. For MPS green status, please visit MPS website under Quality Assurance. MPS and The Future of Analog IC Technology are Registered It is available in an 8-pin TSOT23 package.

PACKAGE REFERENCE TSOT23-8 (1) (4) ABSOLUTE MAXIMUM RATINGS Thermal Resistance JA JC IN Pin .............................................-0.3V to 22V TSOT23-8.............................. 220.... 110.. C/W COMP Pin ......................................-0.3V to 22V Notes: All Other Pins.................................-0.3V to 6.5V 1) Exceeding these ratings may damage the device. (2) o 2) The maximum allowable power dissipation is a function of the Continuous Power Dissipation (T =25 C) A maximum junction temperature T (MAX), the junction-to- J TSOT23-8 ................................................ 0.45W ambient thermal resistance , and the ambient temperature JA Storage Temperature Range.... -65C to 150C T . The maximum allowable continuous power dissipation at A any ambient temperature is calculated by P (MAX) = (T D J (3) (MAX)-T )/ . Exceeding the maximum allowable power A JA Recommended Operating Conditions dissipation will cause excessive die temperature, and the Supply Input Voltage ..........................7V to 20V regulator will go into thermal shutdown. Internal thermal Maximum Junction Temp. (T )................+125C shutdown circuitry protects the device from permanent J damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7, 4-layer PCB.
