Other Parts Discussed in Thread: TPL5010,
I experienced some difficulties using the TPL5010 (see previous post) as I couldn't get regular WAKE pulse.
I tried to simplify my schematic using the TPL5111. The objective si to turn on the power supply of an MCU at periodic times. When the MCU is done with its work it should turn the power OFF. The cycle should repeat at the frequency chosen according to the resistor attached to DELAY/M_RST.
I'd like to validate the 2 points below to make sure I correctly understood the way the TPL5111 is working.
I assume that we are in Timer mode, i.e. EN/ONE_SHOT is permanently High.
1. After POR, and R_EXT reading, DRVn is set to HIGH automatically.
2. A subsequent High pulse on DONE will force DRVn to Low. Then, DRVn will turn high again after the t_IP delay (delay set by R_EXT)
Is this correct?
The target schematic is as follows
