PT7M6315US Supervisory Circuit
2021-08-28
●Description:
■The series is designed to monitor power supplies in μP and digital systems.It provides excellent circuit reliability and low cost by eliminating external components and adjustments,and a debounced manual reset input.
■This device performs a single function:it asserts a reset signal whenever the Vcc supply voltage falls below a preset threshold or whenever manual reset is asserted.Reset remains asserted for an internally programmed interval(reset timeout period)after Vcc has risen above the reset threshold or manual reset is deasserted.
■The PT7M6315USxx devices are open-drain RESET output.They can pulled up to voltage higher than Vcc.
■The serials come with factory-trimmed,reset threshold voltages in 100mV increments from 1.8V to 5V.Preset timeout periods of 200ms(typ.)for PT7M6315USxxD3,1570ms(typ.)for PT7M6315USxxD4,and 26ms for PT7M6315USxxD2 are available.
●Features:
■Highly Accurate:±1.5%(25ºC)
■Detect Voltage Range: 1.8V to 5V in 100mV Increments
■Operating Voltage Range: 1.0V~5.5V
■Operating Temperature Range:-40ºC to +85ºC
■Detect Voltage Temperature Characteristics: ±2.5% ×TYP
■Output Configuration:N-Channel Open Drain
■Totally Lead-Free & Fully ROHS Compliant(Notes 1&2)
■Halogen and Antimony Free "Green"Device(Note 3)
■For automotive applications requiring specific change control(i.e. parts qualified to AEC-Q100/101/200,PPAP capable,and manufactured in IATF 16949 certified facilities),please contact us or your local Diodes representative.
