Product Information

Description

The UCC3952EVM-009 evaluation module provides complete protection for a single lithium-ion cell, including overcharge, overdischarge and short-circuit protection. Note that the UCC3952, using an internal MOSFET switch, requires only a single external decoupling capacitor to provide a complete protection solution.

Bypass capacitor C1 is the only required external component. However, an optional capacitor C2 (installed) provides an increased level of protection against ESD and short circuits. By delaying the recovery from a shorted pack output, C2 increases the level of protection under conditions of intermittent short circuits. Further protection against voltage transients may be added by installing provisional capacitor C3.

Features

UCC3952EVM-009 enhanced single cell lithium-ion battery protection IC EVM features include:

  • Small (5.5mm x 22.5mm) two-sided board with only two components
  • Integrated low-impedance MOSFET switch and current sensor (50 milli ohms typical)
  • Overcharge protection, with built-in 1.5-second time delay (typical)
  • High accuracy +/-1.0% tolerance on overcharge threshold (over temperature)
  • Four standard overcharge thresholds are available (4.20V, 4.25V, 4.30V, or 4.35V)
  • Overdischarge protection, with built-in 15-ms time delay (typical)
  • Overload/short-circuit protection with built-in 1.5-ms time delay (typical)
  • Automatic recovery from short circuit when load is removed
  • Reverse charger protection (up to -8V)
  • Runaway charger protection (up to +16V)
  • Overtemp protection
  • Low operating current of 5 microamps (typical)
  • Low sleep-mode current of 1.5 microamps (typical)
