STEVAL-ISA076V1:Battery charger demonstration board with integrated power switch for Li-ION/Li-POLYMER based on the L6924D

The STEVAL-ISA076V1 demonstration board is based on the L6924D battery charger system with integrated power switch. The L6924D device is a fully monolithic battery charger dedicated to single-cell lithium-ion polymer (Li-Pol) battery packs, and is the ideal solution for space-limited applications such as PDAs, handheld equipment, cellular phones, and digital cameras.

When an external voltage-regulated wall adapter is used, the L6924D works in linear mode, and charges the battery using a constant current/constant voltage (CC/CV) profile.

When a current-limited adapter is used, the device can operate in quasi-pulse mode, dramatically reducing power dissipation.

Key Features

  • Operating input voltage up to 12 V
  • Fully integrated solution with power MOSFET, reverse blocking diode, sense resistor, and thermal control
  • Both linear and quasi-pulse operation
  • Programmable charge current both in fast charge (up to 1 A) and in pre-charge mode
  • Selectable 4.1 V and 4.2 V output voltage (±1% accuracy)
  • Programmable termination current
  • Programmable pre-charge mode voltage threshold
  • Programmable charge timer
  • Multifunction pin for flexible charge process termination
  • Status outputs to drive LEDs or host processor interface
  • Battery absence detection
  • Closed loop thermal control
  • NTC or PTC thermistor interface for battery temperature monitoring and protection
  • RoHS compliant
