PT7M6518-6550(CL/CH /NL) Voltage Detector with Adjustable Delay Time Features Description Operate from VCC of 1.2V to 5.5V Capacitor-Adjustable Delay Active-High/-Low Output Options Open-Drain /Push-Pull Output Options Detect Voltage Threshold Accurate: 2.5% in full Temperature from -40°C to +85°C  Low Supply Current (2µA, Typ.)  Ultra-Small 4-Pin UDFN Package or SOT23-5 Package or SC70-4 package The PT7M6518-6550 is a family of small, low-power, voltage-monitoring circuits with adjustable delay time capability. PT7M65xx series features a highly accurate under voltage detector with hysteresis and an externally programmable time delay generator. This combination of features prevents erratic system reset operation. PT7M65xx series provide external capacitor to adjust for set up delay time. All series operate from a 1.2V to 5.5V supply voltage and are fully specified over the -40°C to +85°C operating temperature range. This family is available in ultra-small 4-pin UDFN (1.6mm x 1.6mm) and SC70-4 and SOT23-5 packages.      Applications      Computers/Servers/Networking Medical Equipment Critical µP Monitoring Intelligent Instruments Set-Top Boxes/Portable Equipment Pin Configuration Pin Description Name Type RST O RST O GND P VCC P Cd I/O Description Active Low Reset Output: RST is asserted to LOW when VCC drops below voltage threshold VTH- value (PT7M65xxCL/NL). PT7M65xxCL output with push-pull. PT7M65xxNLoutput with open-drain which requires external pullup resistance. Active High Reset Output. RST is asserted High when VCC drops below voltage threshold VTH- voltage (PT7M65xxCH). PT7M65xxCH output with push-pull. Ground. Supply Voltage. Operation voltage from 1.2V to 5.5V. By pass 0.1uF ceramic capacitor to GND for noise decoupling. Capacitor Delay. Adjustable. Connect an external capacitor from Cd pin to GND to set the Reset inactive delay time (timeout period) after VCC rise over voltage threshold V TH+. Do not short Cd pin to GND directly. The delay time equation as tdelay=Cd(µF)×4×106µs +40µs.

Internal 250nA sourcing will charge the external cap throw Cd pin when VCC is rise above VTH+, and reset output will disalert after Cd pin voltage is reaches 1V. This delay time is tdelay=Cd (µF) ×4×106µs +40µs. For example, if Cd=1nF, the tdelay=0.001×4×106 µs +40µs=4040µs. Cd pin voltage will be discharged when reset output is assert ok at Vcc falls below Vth-, the discharge resistance is about 200Ω.
