TPS389030DSET is a voltage supervisor with open drain active-low reset. It has an integrated power-on reset in a tiny SOT23-6 and 2x2x0.75mm DFN2 Exposed Pad package. It is a highly precise voltage monitor with a ±2.3mV (max) temperature-compensated delta V threshold accuracy, device-power-on capability, and reset timeout functionality. This device has a reset threshold accuracy of 120mV and an open drain active-low output stage capable of sinking 29mA. It also has a low quiescent current of 0.3uA (max).

This device has a wide application range making it highly suitable for battery-powered systems, i.e. wearables, IoT and medical devices. It is also suited to applications requiringlight loads, such as application processor cores. Furthermore, it is particularly useful in monitoring and safeguarding a variety of battery or switching power supplies.

Designed especially for low power consumption and low voltage applications, the TPS389030DSET operates in direct connection to the power supply. It has an internal resistor-divider method to monitor a specific target voltage with an output active high or active low upon detection of an event or condition. During normal operation, its integrated power-on reset is asserted until the device is powered up and its internal oscillator has a stable frequency.

The device offers advanced features such as adjustable delay to reset and advanced reset timeout. The adjustable delay to reset allows the system to power up quickly, while the advanced reset timeout enables graceful shutdown and recovery in system malfunctions. Moreover, this device offers programmable reset thresholds for factory setup and overvoltage protection for systems up to +7V.

The TPS389030DSET is an embedded supervisor IC with an internal voltage reference so that a higher tolerance can be achieved and accuracy improved. It has a low quiescent current and is an ideal solution for battery-powered applications. With its integrated delay to reset and advanced reset timeout, it provides robust protection for current-limited and overvoltage events. It offers excellent performance and is a suitable choice for multiple monitoring and safeguarding applications in the field of low voltage, low power consumption systems.
