SP720
Peak Transient Current Capability of the SP720
The peak transient current capability rises sharply as the width of the
current pulse narrows. Destructive testing was done to fully evaluate the
SP720’s ability to withstand a wide range of transient current pulses. The
circuit used to generate current pulses is shown in Figure 5.
The test circuit of Figure 5 is shown with a positive pulse input. For a
negative pulse input, the (-) current pulse input goes to an SP720 ‘IN’
input pin and the (+) current pulse input goes to the SP720 V- pin. The
V+ to V- supply of the SP720 must be allowed to float. (i.e., It is not tied
to the ground reference of the current pulse generator.) Figure 6 shows
the point of overstress as defined by increased leakage in excess of the
data sheet published limits.
The maximum peak input current capability is dependent on the V+ to V-
voltage supply level, improving as the supply voltage is reduced. Values
of 0, 5, 15 and 30 voltages are shown. The safe operating range of the
transient peak current should be limited to no more than 75% of the
measured overstress level for any given pulse width as shown in Figure 6.
When adjacent input pins are paralleled, the sustained peak current
capability is increased to nearly twice that of a single pin. For compari-
son, tests were run using dual pin combinations 1+2, 3+4, 5+6, 7+9,
10+11, 12+13 and 14+15.

The overstress curve is shown in Figure 6 for a 15V supply condition. The
dual pins are capable of 10A peak current for a 10µs pulse and 4A peak
current for a 1ms pulse. The complete for single pulse peak current vs.
pulse width time ranging up to 1 second are shown in Figure 6.
