ZHCSQ68A May 2022 – December 2022 TLIN1431-Q1
PRODUCTION DATA
When the TLIN1431x-Q1 encounters a wake up event from the LIN bus the device transitions to restart mode. In restart mode, the LDO is turned on and ramps until VCC > UVCC at which time the device enters either Normal mode, Fast mode or Standby mode depending upon the device control method. In Restart mode, RXD is pulled high. After VCC has exceeded UVCC for tRSTN_act, the device transitions to standby mode and RXD is latched low. Once the device enters normal mode, the RXD pin releases the wake up request signal and the RXD pin then reflects the receiver output from the LIN bus. RXD can be programmed to toggle low or high when in standby mode from a wake event.
