Application note Using the STM6600, STM6601 smart push-button on/off controller. This application note provides a detailed description of the primary applications and benefits of the STM6600-STM6601.
The STM6600 and STM6601 are smart on/off controller devices designed for easy and safe control of applications using one or two push-buttons. They allow systems to securely start, power down, or reset in case of a non-responding application, making them suitable for terminals, audio/video players, smartphones, and other portable devices.
The device monitors the state of connected push-buttons and ensures sufficient supply voltage via an enable output that controls power through MOSFETs or regulators. Key features include a precise 1.5 V voltage reference with +1% accuracy and very low current consumption (6 µA in normal operation, 0.6 µA in standby). The document details pin descriptions, timing sequences for safe power-up and reset, glitch immunity, and various button connection configurations.
These devices allow easy and safe control of applications run with one or two push-buttons by securely starting or powering down a system and also resetting the processor or disabling power in case of a non-responding application.
The device offers a precise 1.5 V voltage reference with very tight accuracy of +1%.
