powersmart ps3150 module data sheet updated 13 september 2001 3 www.powersmart.com copyright powersmart, inc., 2001 general description the ps3150 module is a sbs v1.1 compliant smart battery controller. the module is designed to operate in a battery pack consisting of three or four series connected lithium ion cells. the module consists of three major circuit sections - the powersmart ps331 smbus fuel gauge, mitsumi mm1253/4 based primary safety circuit and a secondary safety circuit controlled by the ps331 to provide backup to the mm1253/4. functional description p3 fuel gauge - the module fuel gauge provides state-of-charge (soc) and battery status data in accordance with the sbdata and smbus standards version 1.1. the p s331 monitors the cell voltages, battery temperature, and current to determine soc and battery status. the ps331 also provides remaining_time, terminate_charge, and terminate_discharge alarms when the battery is fully discharged, fully charged or is under conditions of over-temperature, over-voltage or overdischarge. the state-of- charge calculations are compensated for cell self discharge. the remaining time calculation is compensated for temperature and discharge rate. an additional correction is made in the soc for the estimated integration errors, reported as max_error. the parameters for determining battery status flags and alarm thresholds are all programmable as is the battery design capacity and the battery performance model data. please refer to the ?p3 users guide? and the ?ps331 technical data sheet? for details on programming the p3 serial eeprom data (programmable eeprom data is capitalized in this text for clarity). primary safety -the primary safety circuit provides cell protection from conditions of overcharge, overdischarge and overcurrent. the analog ic mm1253/4 from mitsumi measures individual cell voltages and voltage across the discharge fet. these measures are compared against internal reference values and the gates of two p-channel power mosfets are controlled based on the comparison results. secondary safety ? the second level of safety protection is activated by safeout (pin 21) of the ps331. this pin is activated whenever any individual cell voltage is measured above a programmable limit. an n- channel mosfet is turned on and allows current to pass through the resistive heater section of a fuse. this heating opens the fuse, permanently disabling the pack from further charge or discharge.
