PRODUCTION DATA
The manual reset input allows a processor or other logic circuits to initiate a reset. In this section MR is a generic reference to (CTR / MR). A logic low on MR causes RESET to assert on reset output. After MR is left floating, RESET will release the reset if the voltage at SENSE pin is at nominal voltage. MR should not be driven high, this pin should be left floating or connected to a capacitor to GND, this pin can be left unconnected if is not used.
If the logic driving the MR cannot tri-state (floating and GND) then a logic-level FET should be used as illustrated in Figure 8-8.
MR | SENSE ON NOMINAL VOLTAGE | RESET STATUS |
---|---|---|
Low | Yes | Reset asserted |
Floating | Yes | Fast reset release when SENSE voltage goes back to nominal voltage |
Capacitor | Yes | Programmable reset time delay |
High | Yes | NOT Recommended |
