BIDIRECTIONAL RESET PINS

Some microcontrollers have bidirectional reset pins that act as both inputs and outputs. In a situation where both

the TLV810 and the microcontroller are attempting to drive the RESET line, a series resistor should be placed

between the output of the TLV810 and the RESET pin of the microcontroller to protect against excessive current

flow. Figure 9 shows the connection of the TLV810 to a microcontroller using a series resistor to drive a

bidirectional RESET line.
