3.2 EVM Jumpers
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 V
mon
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 t
D
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 t
D
.
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 t
D
.
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.
