1 / 22 page  - 1 - TS52001 Version 1.3 Specifications subject to change WWW.TRIUNESYSTEMS.COM Copyright © 2011, Triune Systems, LLC DESCRIPTION FEATURES Utilizes a temperature-independent PV MPPT-Lite™ regulation scheme VBAT reverse current blocking Programmable temperature-compensated termination voltage with +/- 1% tolerance Up to 1.5A of continuous output current in Full Charge Constant-Current (CC) mode User programmable charging current High efficiency – up to 92% at typical load Current mode PWM control in constant voltage Supervisor for VBAT reported at the nFLT pin Input supply under-voltage lockout Full protection for VBAT over-current, over-temp, over-voltage, and charging timeout Charge status indication I2C program interface with EEPROM registers SUMMARY SPECIFICATIONS Wide input voltage range: 4.0V to 8.1V Packaged in a 16pin QFN (4x4) TYPICAL APPLICATION GND EN VTHERM SW PG VBAT SCL PGND COUT LOUT RSENSE RREF VIN SDA VTH_REF Photovoltaic Cells VSENSE Battery RTHM RPULLUP (optional) VDD RPULLUP (optional) VDD CIN VDD CVdd The TS52001 is a DC/DC synchronous switching Li- ion Battery Charger with fully integrated power switches, internal compensation, and full fault protection. The TS52001 utilizes a temperature- independent photovoltaic Maximum Power Point Tracking (MPPT-Lite™) calculator to optimize power output from the source during Full Charge Constant- Current (CC) mode. The switching frequency of 1MHz enables the use of small filter components, resulting in smaller board space and reduced BOM costs. In Full Charge Constant-Current mode the duty cycle is controlled by the MPPT-Lite™ regulator. Once termination voltage is reached, the regulator operates in voltage mode. When the regulator is disabled (EN is low), the device draws 10uA quiescent current. The TS52001 includes supervisory reporting through the nFLT (Inverted Fault) open drain output to interface other components in the system. Device programming is achieved by an I²C interface through SCL and SDA pins. APPLICATIONS Portable solar chargers Off-grid systems Wireless sensor networks Smoke detectors HVAC controls High Efficiency Li-Ion Battery Charger for Photovoltaic Sources nFLT TS52001 |
