AMIS-39100 Datasheet, PDF (9/12 Pages) AMI SEMICONDUCTOR – Octal High Side Driver with Protection

AMIS−39100
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
VB−1V on all HS driver outputs. (all drivers are activated, pure resistive
load 35 mA on all outputs)
