NSE34050D: Automotive 40V Dual Channel 50mΩ Smart High-side Switch
The NSE34xxx/NSE35xxx series high-side switches are designed for driving various traditional resistive, inductive, and halogen lamp loads in systems like automotive BCMs, while also being well-suited for handling large capacitive loads commonly found in first and second-level distribution in Zonal Control Units (ZCUs). These series offer options for 1, 2, or 4 channels and are available in HSSOP-16/HSSOP-14 packages, with an Rds(on) range from 8mΩ to 140mΩ. The chips feature precise current sensing, ideal for fault diagnosis, protection, and real-time monitoring of load currents. Additionally, the NSE34xxx/NSE35xxx series incorporate comprehensive protection mechanisms, including overcurrent/short-circuit protection, overtemperature protection, overvoltage protection, ground and power loss protection, reverse polarity protection, and open-load detection.The NSE34xxx and NSE35xxx series products are AEC-Q100 qualified and certified to AEC-Q100-012 level A, ensuring over a million cycles of short-circuit and overcurrent protection.
