詳細說明
The L9963E is a Li-ion battery monitoring and protecting chip for high-reliability automotive applications and energy storage systems. Up to 14 stacked battery cells can be monitored to meet the requirements of 48 V and higher voltage systems.Each cell voltage is measured with high accuracy, as well as the current for the on-chip coulomb counting. The device can monitor up to 7 NTCs. The information is transmitted through SPI communication or isolated interface.Multiple L9963E can be connected in a daisy chain and communicate with one host processor via the transformer isolated interfaces, featuring high-speed, low EMI, long distance, and reliable data transmission.Passive balancing with programmable channel selection is offered in both normal and low power mode (silent balance). The balancing can be terminated automatically based on internal timer interrupt. Nine GPIOs are integrated for external monitoring and control. The L9963E features a comprehensive set of fault detection and notification functions to meet the safety standard requirements.
主要特徵
- Low power single-wire high-speed CAN transceiver
- Prevents CAN network nodes from being damaged by electrostatic discharge
- Offers a 50 V capability on the bus pin
- Compliant with ISO 11898-2:2016
- Provides thermal protection and undervoltage lockout
- Integrated HV pin for transceiver disconnection
應用
- Automotive lighting systems
- LED driver applications
- Halogen and xenon headlamp systems
- Automotive front lighting
- Interior lighting control systems
