Evaluation Kits

MAX1508EVKIT

Evaluation Kit for the MAX1507, MAX1508

Buy Now View Details

Features and Benefits

  • Simple, Stand-Alone Li+ Charger
  • Safely Precharges Deeply Discharged Li+ Cells
  • 4.25V to 13V Input Voltage Range
  • 7V Overvoltage Protection Threshold
  • Resistor-Programmable Charge Current Up to 0.8A
  • Charge Current Monitored by a Resistor
  • Programmable Die-Temperature Regulation Set Points (MAX1507 Only)
  • Active-Low ACOK Output (MAX1508 Only)
  • Fully Assembled and Tested

Product Details

The MAX1507/MAX1508 evaluation kit (EV kit) is a complete, fully assembled, and tested circuit board that demonstrates the MAX1507 linear battery charger for a single-cell lithium-ion (Li+) battery. To evaluate the MAX1508, U1 must be removed and replaced with a MAX1508 device. The EV kit safely charges a single Li+ battery to 4.2V. The EV kit accepts a power-supply input of 4.25V to 13V, but disables charging when the input voltage exceeds 7V. Jumpers on the EV kit allow adjustments to the die-temperature regulation levels (MAX1507 only) and the ability to disable the charger. An LED on the board indicates the status of the charging cycle.

Applications

  • Bluetooth® Equipment
  • Cell Phones/Cordless Phones
  • Charging Cradles and Docks
  • Digital Cameras and MP3 Players
  • PDAs
  • USB Appliances
