Diodes Incorporated PT7M6130CLC4EX

Overview

PT7M6130CLC4EX from Diodes Incorporated is a precision ultra-low-power voltage detector with 3.0V threshold (±1.5% at 25°C), N-channel open-drain active-low reset output, 1μA supply current at 3.6V, and 17μs propagation delay. It operates from 1.2V to 5.5V across –40°C to +85°C and is used in battery-powered microcontroller supervision, portable medical sensors, and low-voltage IoT node power monitoring.

For engineers reviewing the PT7M6130CLC4EX datasheet, PT7M6130CLC4EX pinout, PT7M6130CLC4EX application, or PT7M6130CLC4EX equivalent, this page delivers verified electrical specs, SC70-4 package mapping, reset timing behavior, hysteresis configuration (5%), and design-critical interface guidance for reliable brown-out detection in space-constrained embedded systems.

Technical Context

This device implements a precision bandgap reference (1.25V), comparator, and internally trimmed resistor network to set VTH− = 3.0V with 5% hysteresis (VTH+ = 3.15V). Its open-drain output requires an external pull-up and asserts RST low when VCC drops below VTH−, holding until VCC exceeds VTH+.

The 17μs typical propagation delay and 1μA quiescent current enable fast, energy-efficient reset generation in always-on subsystems. It supports stable operation down to 1.2V supply and maintains ±2.5% threshold accuracy over full temperature range without external calibration.

Key Specifications

FAQ

What is the function of the NC pin on PT7M6130CLC4EX?

The NC (No Connect) pin in the SC70-4 package has no internal connection and must not be bonded or electrically tied to any net. Per Diodes Incorporated layout guidance, it may be left floating or connected to GND for mechanical stability-never to VCC or signal lines-as doing so risks latch-up or parametric shift.

Can PT7M6130CLC4EX drive a 10kΩ pull-up directly?

Yes. With VOL ≤ 0.3V at 1mA sink current and guaranteed 20mA absolute max output capability, PT7M6130CLC4EX fully supports standard 10kΩ pull-ups to 3.3V or 5V. The resulting RST rise time remains <100ns, well within MCU reset timing budgets.

Does PT7M6130CLC4EX require an external capacitor on VCC?

No external bypass capacitor is required for basic operation, but Diodes Incorporated recommends ≥0.1μF ceramic capacitance near the VCC pin to suppress high-frequency noise that could affect threshold stability-especially in noisy switching regulator environments.

How does hysteresis behave during temperature variation?

Hysteresis remains fixed at 5% (VTH+ = 1.05 × VTH−) across –40°C to +85°C. While VTH− drifts ±2.5% over temperature, the ratio between VTH+ and VTH− is process-trimmed and invariant-ensuring consistent chatter margin regardless of ambient conditions.
