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 = 4µA
- 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)
