Part Number:LMR14020-Q1
Dear Team,
We need to safely disable LMR14020-Q1 in our application to minimize system power consumption. Therefor the LMR shall be enabled only when needed. Our supply voltage max is about 27V. Temp range -40°C to 125°C. We are planning an external pull down resistor to keep the part in sleep mode. A port pin of a 5V MCU will be used to turn on the LMR14020-Q1 EN pin when needed.
Question: What is the maximum value of the external pull down resistor that can be used to safely keep the LMR14020 in sleep mode with the mentioned conditions above and over voltage, temp and process variation. We understand there is a internal current source but unfortunately we don't know the min max specs (eg. max current to GND out of the EN pin)
many thanks
Lutz
