5.1 Jumper Set-Up

Jumper Description

can be powered by the input power supply pin A, Jump J1-2, 3 and J9-2, 3. When it is powered by

the load, pin C, jump J1-1, 2 and J9-1, 2. If A and C are less than 3 V, connect the 5 V to V

, jumper

J1-1 to J2 -2 and J8-1 to J9-2.

Jumper J8 is the gate voltage for the Glitch FET. Jump J13-2, 3 when the PS1 voltage is greater than 5

volts. Jump J13-1, 2 to use the 5 volt supply when PS1 is less than 5 volts.

J14 is used to short out the current limit resistor on glitching the power supply. This jumper is installed

only when the voltage is less than 3 volts and a glitch is not generated because of current limit.

An initial jumper setup is recommended in Table 1 . The module has flexibility to operate in other modes.

Change jumpers to operate in other configurations as required after getting started. After the initial setup,

reference the schematic and set jumpers as required for testing. Other J reference designators on the

schematic are simple connectors.
