AMIS-30623 LIN Microstepping Motordriver
11.0 AC Parameters
The AC parameters are given for Vbb and temperature in their operating ranges.
The LIN transmitter/receiver parameters conform to LIN Protocol Specification Revision 1.3. Unless otherwise specified 8V < V
Load for propagation delay = 1kΩ , Load for slope definitions : [L1] = 1nF / 1kΩ ; [L2] = 6.8nF / 660Ω ; [L3] = 10nF / 510Ω.
