RS4040 High Input Voltage Single Cell Charger 1 FEATURES 3 DESCRIPTIONS • Charge Voltage: 4.20V/4.30V/4.35V The RS4040 is a fully integrated high input voltage • Automatic Recharge Voltage: single-cell Li-Ion battery charger. The charger uses a 4.05V/4.15V/4.20V CC/CV charge profile required by Li-Ion battery. The • No external Blocking Diode Required charger accepts an input voltage up to 19.2V but is • Temperature Sense Function disabled when the input voltage exceeds the OVP • Maximum Voltage Power Input: 19.2V threshold, typically 6.5V, to prevent excessive power • Input Over-Voltage Protection: 6.5V dissipation. • Programmable Charge Current: 4mA~400mA overvoltage protection circuit required in a low input • Programmable Full-of-Charge Current voltage charger. • Status Indication: Charging and Fault The 19.2V rating eliminates the Conditions The charge current and the full-of-charge (FOC) • Fixed Safety Timer current are programmable with external resistors. • OUT Short-Circuit Protection and IREF short When the battery voltage is lower than pre-charge to detection constant current charge transition threshold, the Available in the DFN2X2-8 Package charger preconditions the battery with typically 20% • of the programmed charge current. When the charge 2 APPLICATIONS current reduces to the programmable FOC current • IOT Gadgets level during the CV charge phase, an FOC indication • Wearable Devices is provided by the CHG pin, which is an open-drain • Credential Keys output. • Wireless Remote CHG indication pins allow simple interface to a microprocessor or LEDs.
