SBVS157E April 2011 – December 2020 TLV803 , TLV853
PRODUCTION DATA
Some microcontrollers have bidirectional reset pins that act as both inputs and outputs. In a situation where the TLV803 is pulling the RESET line low while the microcontroller is trying the force the RESET line high, a series resistor should be placed between the output of the TLV803 and the RESET pin of the microcontroller to protect against excessive current flow. Figure 8-3 shows the connection of the TLV803 to a microcontroller using a series resistor to drive a bidirectional RESET line.
