The FS24 is a family of automotive safety mini CAN FD SBC devices with multiple power supply designed to support secure car access applications using ultra-wideband (UWB), near field communication (NFC) and Bluetooth® Low Energy (LE) devices, while maintaining flexibility to fit other small applications requiring low power and CAN FD communication.
This family of devices supports a wide range of applications, offering choices in output voltage setting, physical interface, integrated system-level features to address low power and noise sensitive applications with automotive safety integrity levels up to ASIL B.
The FS24 integrates a battery-connected switched-mode regulator (V1) and a battery-connected linear regulator (V3) to supply microcontrollers, communication devices and others. V1 offers a high-performance switching regulator capable to operating in pulse frequency modulation (PFM) mode and force PWM (FPWM) mode. The mode of operation can be changed using wake pins to optimize noise management.
