13.9 CONTROL PIN CHARACTERISTICS
13.9.1 Asynchronous RESET Pin
T
Notes:
1. Data based on characterization results, not tested in production.
2. The I
sum of I
3. The R
V
4. To guarantee the reset of the device, a minimum pulse has to be applied to the RESET pin. All short pulses applied on
RESET pin with a duration below t
