DESCRIPTION
This device performs a single function: it asserts a reset signal whenever the VCC supply voltage falls below a preset threshold. Reset remains asserted for 200ms after VCC has risen above the reset threshold. PT7M1818/1813 are bidirectional output, allowing it to be directly connected to µP with bidirectional reset inputs. Pin Configuration PT7M1818/1813 1 RST GND 3 2 VCC SOT23-3 PinDESCRIPTION
Name Type RST GND VCC I/O P PDESCRIPTION
Reset Output and Pushbutton Input: RST is asserted when VCC drops below voltage threshold VTH-. Active low. When other devices pull RST low, the reset condition occurs and will remain a reset timeout period after the external signal is off.
