Product Overview

The LTC2937CUHE#PBF is a programmable six channel power supply sequencer and voltage supervisor with EEPROM in 28 pin QFN package. Supplies are enabled or disabled with precise user controlled order and time spacing. To detect power supply output faults during sequencing and monitoring, the LTC2937 accurately monitors supply turn-on/off delays and output voltage levels. In the event of a fault, response actions include complete power supply shutdown and optional restarts. Root cause of power faults are logged to EEPROM. After successful sequencing and supply voltage stabilization, the reset output pulls high to initiate microprocessor or other system activity. To accommodate supply margin testing, the reset output can be disabled. Upon supply turn-off, integrated current sources are available as needed to discharge slowly decaying supplies. Configuration EEPROM supports autonomous operation without software.
  • Time and event based sequencing
  • 12 programmable undervoltage (UV) and overvoltage (OV) comparators (±0.75% accuracy)
  • I2C/SMBus interface and stalled power supply detection
  • Wide input operating voltage range from 4.5V to 16.5V
  • Single wire synchronization allows controller expansion to 50 devices (300 power supplies)
  • Discharge threshold voltage of 400mV (high and low range)
  • EEPROM specified over entire temperature range, rated to 85°C, 10K writes and 20year retention
  • Supported by LTpowerPlay GUI reset
  • Comparator propagation delay of 35μs (2 LSB overdrive of configured threshold)
  • Operating junction temperature range from 0°C to 70°C
