TLIN1431-Q1
Overview
The TLIN1431x-Q1 is a local interconnect network (LIN) system basis chip (SBC) that integrates a watchdog, high-side switch, limp home capability and highly configurable WAKE input pin. The device selfdetermines the control method, pin or serial peripheral interface (SPI), at power up.
- AEC-Q100 (Grade 1): Qualified for automotive applications
- Functional safety-capable - Documentation available to aid functional safety system design
- Local interconnect network (LIN) physical layer specification LIN 2.2A, ISO 17987-4:2016 and SAE J2602:2021 compliant
- Integrated watchdog supervisor configurable by pin or serial peripheral interface, SPI
- Enhanced features supporting 12-V applications - ±58 V LIN bus fault protection - 3.3 V (TLIN14313-Q1) or 5 V (TLIN14315-Q1) LDO output supporting 125 mA from 12 V supply - High-side switch with open load and short circuit detection controlled by 10-bit PWM or timer - LIMP pin configurable as a high-side switch - Configurable WAKE pin supporting different input thresholds or methods - Sleep mode: ultra-low current consumption allows wake up event from:
- LIN bus
- Local wake up through WAKE - Cyclic and static sensing
- Protection Features: - ESD protection - Under voltage protection on VSUP and VCC - TXD dominant time out (DTO) protection - Thermal shutdown protection
- Integrated battery voltage monitor
- Available in leadless QFN (20) package with improved automated optical inspection (AOI) capability space
