Pin N° Pin name Function
1 DIAG1
DIAGNOSTIC 1 output. This open drain reports the IC working
conditions. (See Diagnostic truth Ta b l e 7)
2 DIAG2
DIAGNOSTIC 2 output. This open drain reports the IC working
conditions. (See Diagnostic truth Ta b l e 7)
3 IN- Comparator non inverting input
4 IN+ Comparator inverting input
5 OUTSTATUS
This current source output is capable of driving a LED to signal the
status of the output pin. The pin is active (source current) when the
output pin is considered high (See Figure 3)
6 GND Ground
7 ON-DELAY Programmable ON time interval duration during short circuit operation
8 RSC Current limitation setting.
9 OUTPUT High Side output with built-in current limitation
10 V
S
Supply Volatge Input, the value of the supply voltage is monitored to
detect under voltage condition
11 OUTPUT High Side output with built-in current limitation
