Electrical Characteristics (continued)
(V
Typical values are at T
1) The WK pin is configurable as input or as output which sent a trigger pulse on received trigger telegram. To configure this
2) The RESET pin is an open drain input/output with pull current source to V
3) The input at pin RESET is not active in reset and startup modes and in case of low V
4) In case of RESET activation by E981.03.
ELMOS Semiconductor AG reserves the right to change the detail specifications as may be required to permit improvements in the design of its products.
