PT7M1818
PT7M1818 is Supervisory Circuit manufactured by Pericom Semiconductor.
Features - Highly accurate: 1.5% (25°C) - Accurate power monitoring: 2.5V, 2.9V, 3.0V (PT7M1818), and 4.1, 4.3, 4.6V (PT7M1813) - Operating voltage range: 1.0V ~ 5.5V - Operating temperature range: -40°C to + 85°C - Detect voltage temperature characteristics: 2.5%  - Efficient open-drain output with internal 5k pull-up resistor - Maintains reset for 200ms after VCC returns to an in- tolerance condition Description The series are designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external ponents and adjustments. 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 Pin Description Name Type GND VCC I/O Description 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.
