Name
Function
1
DIAG1
DIAGNOSTIC 1 output. This open drain reports the IC working conditions. (See
Diagnostic truth table)
2
DIAG1
DIAGNOSTIC 2 output. This open drain reports the IC working conditions. (See
Diagnostic truth table)
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 fig 1)
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
VS
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
