3.6.3 Pulse Current Source
The pulse current source is provided to demonstrate the PAC1710 and PAC1720
devices’ ability to detect current spikes of varying amplitude and duration. The current
source is activated using momentary switch SW4 Pulse Trigger. Rotary switch SW2
Pulse Amp Adj, in conjunction with the J15 jumper position which increases the
dynamic range of the pulse width, sets the pulse duration as shown in
Table 3-6 . Single
pulse current consumption is shown in Table 3-7 .
