3.2 EVM Jumpers

Table 3-2 lists the jumpers on the TLV841EVM. As ordered, the EVM will have eight (8) jumpers and five (5) shunts installed.

Table 3-2 List of Onboard Jumpers
JUMPER JUMPER CONFIGUATION DESCRIPTION
J1 Shunted Connect a shunt to jumper J1 to use R1 as the pull-up resistor on the output RESET pin.
J2 N/A Both pins on J2 are connected together. Connect either pin on jumper J2 to the input power supply.
J3 N/A Both pins on J3 are connected together. Use either pin on jumper J3 to monitor the output RESET pin.
J4 Shunted Connect a shunt to jumper J4 to short Vmon to VDD
J5 N/A Both pins on J5 are connected together. Connect either pin on jumper J5 to connect to ground.
J6 Open (Default) For TLV841C: If no shunt is placed on J6, the reset time delay tD defaults to the minimum RESET time delay set internally by the TLV841C.
Pin 1 [C2] to Pin 2 [CT]

For TLV841C: Connect a shunt to jumper J6 for different RESET time delay configurations.
OPTIONAL: For TLV841S: Jumper J6 allows the user the option to connect C2 to the SENSE input, as a bypass capacitor, to reduce the sensitivity of transient voltages on the monitored signal. Connecting C2 to the SENSE input will affect the timing specs such as reset time delay tD.
Pin 2 [CT] to Pin 3 [C3] For TLV841C: Connect a shunt to jumper J6 for different RESET time delay configurations.
OPTIONAL: For TLV841S: Jumper J6 allows the user the option to connect C3 to the SENSE input, as a bypass capacitor, to reduce the sensitivity of transient voltages on the monitored signal. Connecting C3 to the SENSE input will affect the timing specs such as reset time delay tD.
J7 Shunted
Pin 1 to Pin 2		 For TLV841S and TLV841M: Connect a shunt to jumper J7 to connect different configurations (Rdiv or MR) from J8.
For TLV841C: Remove shunt to jumper J7 for this option.
J8 Open
Pin 1 [MR] to Pin 2 [GND]		 Connect the shunt to jumper J8 for different configurations. Connect the shunt from MR (Manually Reset) and to GND.
Shunted (Default)
Pin 2 [GND] to Pin 3 [Rdiv]		 Connect the shunt to jumper J8 for different configurations. Connect the shunt to Rdiv and GND for the voltage divider configuration.
