APPLICATIONS INFORMATION
operation of gated protectors
The following SLIC circuit definitions are used in this data sheet:
V
BAT
— Package pin label for the battery supply voltage.
V
Bat
— Voltage applied to the V
BAT
pin.
V
B
— Negative power supply voltage applied to the V
BAT
pin via an isolation diode. This voltage is also the
gate reference voltage, V
GG
, of the TISPPBLx. When the isolation diode, D1, is conducting, then
V
Bat
= V
B
+ 0.7.
The isolation diode, D1 in Figure 13, is to prevent a damaging current flowing into the SLIC substrate (V
BAT
pin) if the V
Bat
voltage becomes more negative than the V
B
supply during a negative overvoltage condition.
Each SLIC needs an isolation diode from the V
B
voltage supply.
negative overvoltages and the diode sections limit positive overvoltages.
Negative overvoltages (Figure 13) are initially clipped close to the SLIC negative supply rail value (V
B
) by the
conduction of the transistor base-emitter and the thyristor gate-cathode junctions. If sufficient current is
available from the overvoltage, then the thyristor will crowbar into a low voltage ground referenced on-state
condition. As the overvoltage subsides the high holding current of the crowbar thyristor prevents d.c. latchup.
