The TLC7725QDR is a voltage supervisor IC, specially designed to prevent malfunction due to out of tolerance brown-outs, overvoltages, undershoots, and other power supply problems. It monitors both a power supply and an input voltage or input voltage range, and reset output control signals to an external circuit when any of the monitored values goes out of tolerance. This makes the supervisor IC ideal for use as an under-voltage/over-voltage protection circuit, as well as for applications that require a reset for digital circuit operation, such as in microcontrollers, DSPs and other digital devices.
TLC7725QDR is a quad-channel regulator IC from Texas Instruments. It is a voltage supervisor IC that monitors four voltage levels framed by two analog references, and provides a reset signal. The TLC7725QDR is available in a 4-ball WLCSP and a 8-lead MSOP package. Operating in temperature ranges of -40°C to +85°C, the supervisor IC provides excellent temperature-related stability with fewer configuration settings.
The TLC7725QDR is particularly useful in systems with more than one power rail, such as systems using multiple voltage levels, because it is capable of monitoring multiple voltage levels simultaneously. This simplifies and speeds up the process of monitoring and resetting the system, allowing it to react more quickly to changing power conditions.
The TLC7725QDR provides a number of features that make it suitable for a wide range of applications. It is a low voltage supervisor IC, operating down to 1.8V, and it is also capable of operating over a wide range of temperatures, from -40°C to +85°C. It is designed to provide an accurate reset signal, and it operates at low power, with low power consumption, making it suitable for battery powered or energy-harvesting applications. It is also very easy to configure, and all configuration settings are stored in EEPROM, meaning that settings can be easily changed or restored in the event of a power outage.
The TLC7725QDR is easy to use, and is configured with two analog references. Adjusting the reference voltage range necessarily adjusts the set point of monitored voltages in the system, resulting in quicker response times from the supervisor IC’s reset signal. The TLC7725QDR can provide an active-high or active-low reset signal, which is configurable for each channel. This ensures that the reset signal is more in line with the application’s requirements, for a better overall system performance.
The supervisor IC also features an adjustable delay, allowing the user to fine-tune the amount of time before the reset signal is sent out from the monitor IC. This ensures that the system has enough time to react to an abnormal voltage value before the reset signal is sent. The supervisor IC also has an optional push-pull output, which serves to provide an improved reset signal, as well as providing an improved power-on reset signal.
In short, the TLC7725QDR is a reliable, energy-efficient voltage supervisor IC that can be used in a variety of applications, from microcontroller and DSP systems to batteries and energy-harvesting systems. It is easy to configure and provides an accurate reset signal, ensuring that the system is quickly and reliably reset in the event of a power fault.
