Note 1:
Production tested at +25°C only. Over temperature limits are guaranteed by design, not production tested.
Note 2: RESET (RESET)
open.
Note 4:
Standard version for tPOR is 200ms (typ), available at all times. Other option (1.6ms, 25ms, 1600ms) are available
by mask option and upon minimum order quantity. Please contact EM sales.
Note 5:
Pulse width must be greater than 1
μs to ensure the RESET (RESET) to go active.
