Hello team,
Can you reply the following questions of TPS3430-Q1?
-. When TPS3430-Q1 is always powered on in the MCU’s sleep mode which can’t give WDI, does the RESET (WDO) by TPS3430-Q1 watchdog continue to operate?
-. It seems there is no sleep mode of TPS3430-Q1. When watchdog is disabled, what is the current consumption?
-. Should the VDD of TPS3430-Q1 be equal to MCU VDD due to I/O level? Otherwise, is it possible to use the different voltage?
Best Regards,
Sam Lee
Hi Sam,
-. When TPS3430-Q1 is always powered on in the MCU’s sleep mode which can’t give WDI, does the RESET (WDO) by TPS3430-Q1 watchdog continue to operate?
Yes as long as the TPS3430-Q1 is powered and the watchdog is enabled the WDO will continue to operate.
-. It seems there is no sleep mode of TPS3430-Q1. When watchdog is disabled, what is the current consumption?
The current consumption when watchdog is disabled is rated the same as when watchdog is enabled, 10 µA (Typical) & 19 µA (Max)
*note: If the watchdog is disabled, then WDI cannot be left unconnected and must be driven to either VDD or GND. This is to ensure there is no increase in supply current.*
-. Should the VDD of TPS3430-Q1 be equal to MCU VDD due to I/O level? Otherwise, is it possible to use the different voltage?
It is possible to use a different voltage as long as it is within Supply voltage recommended operating conditions, 1.6 V to 6.5 V.
Thanks,
Joshua
