onsemi NCS35011 5S Battery Protectors

onsemi NCS35011 5S Battery Protectors are ultra-low power protection integrated circuits that manage lithium-ion batteries from three to five cells. The protectors offer accurate battery voltage indications up to 5 LED outputs.

Each cell in the battery pack is monitored for overvoltage and undervoltage conditions. When an overvoltage is detected, the ODI pin will assert, indicating a fault condition, and stay asserted until the fault is cleared.

During an under-voltage condition, the UDI pin will also assert indicating the fault but will have a pre-set pulse width in the protector. Over- and under-voltage detections have a hard-coded pre-set delay time before fault indication.

Features

  • Over-Voltage (OV) and Under-Voltage (UV) detection
  • Protection for 3, 4, and 5 series cells
  • State of Charge (SoC) indication with high voltage tolerant LED drivers
  • Configurable fault outputs (active high or low for push-pull or open-drain)
  • High-accuracy voltage measurement of ±5mV
  • Low power consumption Icc = 4A
  • Input BAT voltage range from 5V to 28V, tolerant to 70V for increased immunity to surge
  • Extended junction temperature range to +125°C
  • These devices are Pb-free and RoHS compliant

Applications

  • Secondary protection
  • Power and gardening tools
  • Portable/autonomous equipment (cleaners, mowers, motive, medical)
