1 / 16 page  - 1 - TS52003 Version 1.2 Specifications subject to change WWW.TRIUNESYSTEMS.COM Copyright © 2011, Triune Systems, LLC DESCRIPTION FEATURES TYPICAL APPLICATION GND EN SW nFLT VOUT SCL PGND COUT LOUT RSENSE VIN SDA Photovoltaic Cells VSENSE Super Cap RPULLUP (optional) VDD RPULLUP (optional) VDD CIN VDD CVdd TS52003 The TS52003 is a DC/DC synchronous switching Super Capacitor Charger with fully integrated power switches, internal compensation, and full fault protection. The TS52003 utilizes a temperature- independent photovoltaic Maximum Power Point Tracking (MPPT-Lite™) calculator to optimize power output from the source during Full-Charge mode. The switching frequency of 1MHz enables the use of small filter components, which result in smaller board space and reduced BOM costs. In Full-Charge 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 less than 15uA quiescent current from VOUT. The TS52003 integrates a wide range of protection circuitry; including input supply under-voltage lockout, output over-voltage protection, current limit, and thermal shutdown. The TS52003 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. High Efficiency SuperCap Charger for Photovoltaic Sources Utilizes a temperature-independent PV MPPT-Lite™ regulation scheme VOUT reverse current blocking Wide input voltage range: 3.2V to 7.2V Up to 1.5A continuous output current Programmable temperature-compensated termination voltage with a ± 1% tolerance User programmable termination voltage High efficiency – up to 92% at typical load Current mode PWM control in constant voltage Input supply under voltage lockout Full protection for V OUT over-voltage Device over-current and over-temperature protection I2C program interface with EEPROM registers V OUT reverse current blocking Charge status indication SUMMARY SPECIFICATIONS Packaged in a 16pin QFN (4x4) APPLICATIONS Off-grid systems Wireless sensor networks Smoke detectors HVAC controls |
