AMISâ39100
Normal Mode Verification:
⢠The command is the set of eight bits loaded via SPI, which drives the eight HS drivers on or off.
⢠The command is activated with rising edge on WR pin.

Description
T_command_L_max
(Note 14)
Minimum time between two opposite commands for inductive loads and
maximum HS driver current of 275 mA
T_command_R (Note 14)
Minimum time between two opposite commands for resistive loads and
maximum HS driver current of 350 mA
T_PDB_recov
The time between the rising edge on the PDB input and 90 percent of
VBâ1V on all HS driver outputs. (all drivers are activated, pure resistive
load 35 mA on all outputs)
