This document describes the STM6513 Dual push-button Smart ResetTM, which features dual reset outputs and user-selectable setup delay. The product is suitable for applications such as mobile phones, e-books, MP3 players, games, and portable navigation devices that require delayed reset button response for improved system stability.
The STM6513 is a dual push-button Smart Reset device designed for applications requiring delayed reset push-button response to improve system stability. It features two separate delayed Smart Reset inputs (SR0, SR1) that, when taken low simultaneously, provide three user-selectable delayed Smart Reset setup time options of 2 s, 6 s, and 10 s. These options are selected through a three-state TSR input pin. The device generates two reset outputs (RST1 and RST2) simultaneously after the setup delay is met.
| Reset setup delay options | 2, 6, 10 s (min.) |
|---|---|
| Operating voltage | 1.0 V to 5.5 V |
| Supply current | 3 µA |
| Operating temperature | -40 °C to +85 °C |
| Package dimensions | 2 mm x 2 mm x 0.75 mm |
| Reset output RST1 type | active-high, push-pull |
| Reset output RST2 type | active-low, open-drain |
The delay is selected through a three-state TSR input pin: connected to ground for 2 s, left open for 6 s, or connected to V CC for 10 s.
RST1 is an active-high push-pull output, while RST2 is an active-low open-drain output.
Yes, the duration of the output reset pulse t REC1 is user-programmable by an external capacitor, while t REC2 is factory-programmed.
