Supply Voltage for Device "ON"
Supply Voltage for Device "OFF"
(output internally switched to ground)
Sense Limit Voltage (4)
1. G
ON
is measured with V
3
varying from 150mV to 350mV (Pin 5 is grounded)
2. G
is measured with V
varying from 150mV to 350mV (Pin 3 is grounded)
3. When the remote input goes from HIGH to LOW the BU508 is switched off and it remains in this condition for the time t
.
4. The sense input voltage V
is internally limited and results in a limited positive output current I
= g V
limit. Note that due to
the storage time t
of the BU508 limiting of V
S
leads to a reduced base current of the BU508 and the output current I
0
is going to
the positive quiescent current I
O0
