They provide excellent circuit reliability and low cost by eliminating external components and adjustments. The devices perform a single function: assert a reset signal whenever the VCC supply voltage falls below a preset threshold. Reset remains asserted 200ms after VCC has risen above the reset threshold. PT7M1233/1233A are bidirectional output, allowing it to monitor a pushbutton on the reset output. Pin Description Name Type Description RST I/O 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 at least 200ms. GND P Ground VCC P Supply Voltage. 2013-06-0001 PT0195-4 06/17/13 1 ||||...
