8. Limiting values
[1] Equivalent to discharging a 100 pF capacitor through a 1.5 k& series resistor.
[2] Equivalent to discharging a 200 pF capacitor through a 0.75 礖 coil and a 10 & resistor.
9. Thermal characteristics
The graph in
Figure
4 shows the relationship between junction temperature and VSENSE
voltage.
Table 3.
Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are measured with respect to ground
(pin 2); positive currents ow into the chip. The voltage ratings are valid provided other ratings are not violated; current ratings
are valid provided the other ratings are not violated.
