Overview

1.7
Undervoltage lockout (UVLO):
When
V
S
reaches the switch on voltage
V
S ON
the IC becomes active with a hysteresis.
All output transistors are switched off if the supply voltage
V
S
drops below the switch off
value
V
S OFF.
Monitoring Functions
1.8
Various errors like short-circuit to +
V
S
, ground or across the load are detected. All faults
result in turn-OFF of the output stages after a delay of 50
μ
s and setting of the error flag
EF to ground. Changing the inputs resets the error flag.
Protective Function
a. Output Shorted to Ground Detection
If a high side transistor is switched on and its output is shorted to ground, the output
current is internally limited. After a delay of 50
μ
s all outputs will be switched-OFF and
the error flag is set.
b. Output Shorted to +
V
S
Detection
If a low side transistor is switched on and its output is shorted to the supply voltage,
the output current is internally limited. After a delay of 50
μ
s all outputs will be
switched-OFF and the error flag is set.
c. Overload Detection
An internal circuit detects if the current through the low side transistor exceeds the
trippoint
I
SDL
. In this case all outputs are turned off after 50
μ
s and the error flag is set.
d. Overtemperature Protection
At a junction temperature higher than 150
°
C the thermal shutdown turns-OFF, all four
output stages commonly and the error flag is set with a delay.
e. Open Load Detection
The output Q1 has a 10 k
pull-up resistor and the output Q2 has a 10 k
pull-down
resistor. If E1 and E2 are high, all output power stages are turned-OFF. In case of no
load between Q1 and Q2 the output voltage Q1 is
V
S
and Q2 is ground. This state will
be detected by two comparators and an error flag will be set after a delay time of
50
μ
s. Changing the inputs resets the error flip flop.
