Diodes Incorporated PT7M6130NLTA3EX

Overview

PT7M6130NLTA3EX from Pericom Semiconductor is a precision ultra-low-power voltage detector IC with 3.0 V threshold (±1.5% at 25°C), N-channel open-drain active-low reset output, and 17 µs propagation delay. It operates from 1.2 V to 5.5 V supply, supports -40°C to +85°C industrial temperature range, and integrates internal hysteresis (5%) for noise immunity-used in microcontroller supervisory circuits for battery-powered IoT sensors and portable medical devices.

For engineers reviewing the PT7M6130NLTA3EX datasheet, PT7M6130NLTA3EX pinout, PT7M6130NLTA3EX application, or PT7M6130NLTA3EX equivalent, key selection criteria include threshold accuracy over temperature (±2.5% typ), sub-1 µA quiescent current at 3 V, SOT23-3 package compatibility, and open-drain output drive capability up to 20 mA sink current.

Technical Context

The PT7M6130NLTA3EX employs a precision bandgap reference and internally trimmed resistor network to set its 3.0 V detection threshold (VTH−), with hysteresis defined as VTH+ = 1.05 × VTH−. Its comparator-based architecture ensures monotonic trip behavior during power-up/down sequences without external components.

It features a dedicated N-channel open-drain output stage with guaranteed low-level output voltage (VOL ≤ 0.3 V at 4 mA sink) and leakage current < 1 µA, enabling direct interface with pull-up voltages up to VCC. Propagation delay is tightly specified at 17 µs typical under full operating conditions.

FAQ

What is the exact detection threshold voltage and tolerance for PT7M6130NLTA3EX?

The PT7M6130NLTA3EX has a nominal detection threshold (VTH−) of 3.0 V with ±1.5% accuracy at 25°C and ±2.5% over the full -40°C to +85°C operating range. The hysteresis window is fixed at 5%, so VTH+ = 3.15 V. These values are factory-trimmed and do not require external calibration.

Can PT7M6130NLTA3EX operate from a 1.8 V supply?

Yes-PT7M6130NLTA3EX operates from 1.2 V to 5.5 V, fully functional at 1.8 V. At this voltage, supply current remains below 1.3 µA, and the 3.0 V threshold detection remains valid because the internal bandgap reference and comparator are designed to function across the entire supply range.

Is an external pull-up resistor required on the RST pin?

Yes-an external pull-up resistor is mandatory on the RST pin because PT7M6130NLTA3EX uses an N-channel open-drain output. Typical values range from 1 kΩ to 510 kΩ depending on bus capacitance and rise time requirements; 10 kΩ is recommended for general-purpose use with 3.3 V pull-up.

Does PT7M6130NLTA3EX include a built-in reset timeout period?

No-PT7M6130NLTA3EX does not incorporate a programmable or fixed reset timeout. Reset assertion ends immediately when VCC rises above VTH+ (3.15 V). For applications requiring guaranteed minimum reset pulse width, an external RC network or companion timer IC must be used.
