General Remark
Faulty Pulse at DG1
Problem Fix/Workaround
This chapter describes the principal application for which the ATA6823 was designed.
Because Atmel
tion, and environment, no warranties of fitness for a particular purpose are given.
Table 9-1.
A faulty pulse of approximately 100ns appears at pin 16 (DG1), signalizing short circuit condi-
tion, under following circumstances:
General condition: PWM = HIGH
and
detected undervoltage of VBAT (signalized at pin 15 = DG2)
or
detected overvoltage of VBAT (signalized at pin 15 = DG2)
or
detected undervoltage of the charge pump (signalized at pin 15 = DG2)
or
overtemperature shutdown.
Set the software to ignore the faulty pulse.
