PMICs, or power management integrated circuits, are a unique type of integrated circuit that is specifically designed to manage all of the various power-related tasks in the power regulation and control system. The PMIC includes multiple, distributed controllers and supervisors, each with a specific task and working principle. The TLC7703QD is one of these power management integrated circuit supervisors, and it is important to understand its application field and working principle in order to properly use it.

The TLC7703QD is a Texas Instruments’ supervisor IC that provides protection against overvoltage, undervoltage, and runaway conditions in modern electronic devices. It helps keep the device’s power supply from exceeding safe operating limits and ensures reliable operation. This IC is designed to work with 5V to 7V logic voltage and is packaged in either SOIC-20 (4 x 4.4 mm) or DIP-16 (3.9 x 9.7 mm) packages. The TLC7703QD target applications include, but are not limited to, power supply sequencing, brown-out reset in embedded systems, and motor control.

The IC is powered by a 5V-7V logic, and it requires a resistor to monitor the reference voltage of the system. This resistor is connected to the voltage supervisor pin (the RES pin) to create a reference voltage. This reference voltage is compared to an internal threshold voltage to determine if the system is in a low, normal, or high voltage condition. When the voltage level exceeds either of the internal thresholds, an active-low reset signal is issued.

In addition, the TLC7703QD comes with a variety of integrated protection features. These include overvoltage protection (OVP) and undervoltage protection (UVL). OVP protects the device from voltage transients and potential damage from excessive and sudden voltage spikes, while UVL prevents the system from running in an unsafe low voltage condition. The TLC7703QD also has a reverse-bias voltage clamp for robust protection of CMOS inputs, as well as an adjustable Voltage Supervision Timeout (VST) feature to protect from runaway conditions.

The TLC7703QD is an effective and versatile solution for protecting against overvoltage and undervoltage events, as well as runaway conditions in embedded systems. Its integrated protection features, adjustable Voltage Supervision Timeout, and robust design make it an ideal solution for power sequencing and brown-out reset applications. Moreover, its small size and wide supply voltage range makes it well suited for a variety of devices, ranging from small batteries to large appliances.
