Descrição

Tradução por IA

The MAX1666 battery-pack protectors supervise the charging and discharging processes of Li+ battery cells. Designed for 2-, 3-, and 4-cell applications, these devices monitor the voltage across each cell to provide protection against undervoltage, overvoltage, and overcurrent damage. Control pins CGO, TKO, and DSO allow control of external MOSFET gates. This allows fast charging, trickle charging, and discharging processes. The voltage of each cell is measured individually. Also, each cell is measured differentially between every other cell of the pack. The MAX1666 contains a state machine, a voltage regulator, an oscillator, and other logic functions to selectively drive CGO, UVO, TKO, DSO, WRN, and PKF.

  • The MAX1666 provides complete protection against overvoltage, undervoltage, overcharge current, overdischarge current, and cell mismatch for 2-cell to 4-cell lithium-ion (Li+) battery packs.
  • The voltage of each cell in the battery pack is checked and compared to the programmable threshold and to the other cells in the pack.
  • The MAX1666 protects the battery pack in an overcurrent condition by disconnecting the pack from the load at a programmable limit.
  • On-chip power MOSFET drivers control external P-channel MOSFETs to disconnect the cells from external terminals when faults occur.
  • The MAX1666 employs a unique timing scheme that allows three modes of operation for optimal performance and battery power conservation.
  • The MAX1666 can operate in a stand-alone configuration or in conjunction with a microcontroller.
  • It is available in four versions: the S version monitors two Li+ cells, the A and V versions monitor three cells, and the X version monitors four cells.
  • When the charge path is disabled by the charge control pin, the MAX1666A reduces current consumption compared to the MAX1666S/V/X.
  • Overvoltage Protection Programmable Limits from +4.08 to +4.48 Accurate to ±0.5%
  • Undervoltage Protection Programmable Limits from +2.08 to +3.08 Accurate to ±2.5%
  • Cell Mismatch Protection Programmable Limits from 0 to 500mV Accurate to ±10%
  • Overcharge Current Protection
  • Overdischarge Current Protection
  • Low 30μ (typ) Operating Supply Current
  • Low 1μ (max) Standby Current
  • ±28V (max) Input Voltage
  • Available in Small 16-Pin QSOP (MAX1666S) and 20-Pin QSOP (MAX1666A/V/X) Packages
