5 / 7 page - 5 - TS55101 Version 0.5 Specifications subject to change WWW.TRIUNESYSTEMS.COM Copyright © 2013, Triune Systems, LLC Triune Systems Proprietary and Confidential Information DO NOT DUPLICATE PRODUCT PREVIEW FUNCTIONAL DESCRIPTION The TS55101 is a fully-integrated Li-Ion battery charger IC based on a highly-efficient switching topology. It includes configurability for termination voltage, charge current and a host of other variables to allow optimum charging conditions for a wide range of Li-Ion batteries. A 1 MHz internal switching frequency facilitates low-cost LC filter combinations. When the battery voltage is below 3.0 volts, the device will enter a pre-charge state and apply a small, programmable charge current to safely charge the battery to a level for which full charge current can be applied. Once the full charge mode has been initiated, the device will maximize available charge current to the battery by adjusting its duty cycle to regulate its input voltage to the MPP voltage of the photovoltaic cell. If sufficient current is available from the PV cell to exceed the safe 1C charge rate of the battery, then the programmable 1C current limit function will take precedence over the MPP control function and the PV cell voltage will rise above the MPP value. When the battery voltage has increased enough to go into maintenance mode, the PWM control loop will force a constant voltage across the battery. Once in constant voltage mode, current is monitored to determine when the battery is fully charged. This regulation voltage as well as the 1C charging current can be set to change based on battery temperature. There are 4 temperature ranges where these can be set independently, 0-10°C, 10-45°C, 45-50°C and 50-60°C. The 0°C and 60°C thresholds will stop charging and have 10 degrees of hysteresis. The intermediate points have 1 degree of hysteresis. |
