FS2401M Datasheet | NXP Semiconductors

description FS2400 is a family of automotive safety system basis chip (SBC) devices with multiple power supplies designed to support secure car access application using ultra-wide band (UWB), near-field munication (NFC), and Bluetooth Low Energy (BLE) devices. The FS2400 can also fit other small applications requiring low power and CAN FD munication. This family of devices supports a wide range of applications, offering a choice of output voltage settings, physical interface, integrated system-level features to address low-power and noise-sensitive applications with automotive safety integrity levels (ASIL) up to ASIL B. The FS2400 integrates a battery-connected switched-mode regulator (V1) and a battery-connected linear regulator (V3) to supply microcontroller, munication devices, and others. V1 offers a high-performance switching regulator capable of operating in Pulse Frequency Modulation (PFM) mode and Force Pulse Width Modulation (FPWM) mode. The mode of operation can be changed using wake pins to optimize noise management. The FS2400 is developed in pliance with the ISO 26262:2018 standard. It includes enhanced safety features , with fail-safe output, being part of a full safety-oriented system, covering ASIL B safety integrity level. The FS2400 is offered in a 5 mm x 5 mm, 32-Ld HVQFN package with wettable flanks. FS2400_SDS Product short data sheet All information provided in this document is subject to legal disclaimers.
