DELAY/M_RST

A resistance in the range between 500 Ω and 170 kΩ needs to be connected to select a valid time interval. At the POR and during the reading of the resistance the DELAY/M_RST is connected to an analog signal chain though a mux. After the reading of the resistance the analog circuit is switched off and the DELAY/RST is connected to a digital circuit.

The manual reset detection is supported with a de-bounce feature which makes the TPL5010 insensitive to the glitches on the DELAY/M_RST pin. When a valid manual reset signal is asserted on the DELAY/M_RST pin, the RSTn signal is asserted LOW after a delay of tM_RST. It remains LOW after a valid manual reset is asserted + tDB + tRSTn. Due to the asynchronous nature of the manual reset signal and its arbitrary duration, the LOW status of the RSTn signal maybe affected by an uncertainty of about ±5 ms.

A valid manual reset puts all the digital output signals at their default values:

  • WAKE = LOW
  • RSTn = asserted LOW
