FS2400_SDS

Fail-safe system basis chip with SMPS and LDO, CAN FD transceiver

1 General 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 communication (NFC), and

Bluetooth Low Energy (BLE) devices. The FS2400 can also fit other small applications requiring low power and

CAN FD communication.

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, communication 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 compliance with the ISO 26262:2018 standard. It includes enhanced safety

features, with fail-safe output, becoming 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.
