TLV803SDBZT

The Texas Instruments TLV803SDBZT is a 3-pin voltage supervisor designed for circuit initialization and timing supervision, particularly in processor-based systems. This device monitors a single supply voltage and asserts an active-low, open-drain reset signal when the voltage falls below a specified threshold. It features a typical threshold voltage of 2.93V and a fixed reset time delay of 200ms. The operating temperature range is -40°C to 125°C.

Packaged in a SOT-23-3 surface-mount package, the TLV803SDBZT is suitable for space-constrained applications. Its low quiescent current of 0.009mA makes it efficient for battery-powered devices. The open-drain output allows for flexible interfacing with various system designs. This supervisor is pin-for-pin compatible with the MAX803, offering an alternative for existing designs.

Key electrical characteristics include monitoring a single voltage supply with multiple available threshold options (2.25V, 2.64V, 2.93V, 4.38V). The reset output is active-low and open-drain, with a minimum reset timeout of 120ms. The device operates over a wide temperature range of -40°C to 125°C, making it robust for various environmental conditions.
