AS8530
Datasheet - Detailed Descr i p ti on
7.8.4 Temporary Shutdown Mode
In this mode, the VCC is pulled down and the LDO is powered down. This mode is introduced to interface with other components which do not
have a pin for the reset functionality. This provides an alternative way to reset those components interfacing with AS8530. This mode is default
disabled but can be enabled by an OTP option. In this mode, all internal modules supplied by the LDO are disabled. Only the oscillator, control
registers are enabled. The VCC output can be temporarily switched off and pulled to VSS. EN signal, RX, TX is pulled low and LIN Transceiver
along with the LIN wake-up circuit is powered down. No remote wake-up functionality is possible. LIN bus enters into recessive state. The
system goes out of this mode to normal mode after the time-out of an internal counter delay (Tshd). Normal mode to temporary shutdown
transition will be controller by register bit in configuration register.
7.8.5 Thermal Shutdown State
If the junction temperature TJ is higher than Tsd, the AS8530 will be switched into the thermal shutdown mode. The transceiver is completely
disabled. No wake-up functionality is available. Window watchdog, TX timeout watchdog, and LDO are completely turned off. Only the over-
temperature monitor would be working. As soon as the temperature returns back to Tret, the system enters normal mode. For more information
on transition, see Table 3.
Note:
L = low state, H = high state, OT = Over-temperature Reset, Uvcc = Undervoltage VCC, Uvbat = Undervoltage VBAT, rwake =remote
wake, X = do not care.
