The Texas Instruments TLV803SDBZR is a compact, low-power voltage supervisor designed to maintain system integrity by monitoring the supply voltage of digital systems. It is an essential component for applications that require a high degree of reliability and operational stability, such as microprocessor or microcontroller-based systems, where it ensures that the system operates within the specified voltage range.

This voltage supervisor comes in a small, 3-pin SOT-23 package, making it an ideal choice for space-constrained applications. It features a fixed-sense threshold voltage of 2.93V, which is preset by the manufacturer, ensuring that no external components are required for threshold setting. This simplifies the design and reduces the overall component count.

The TLV803SDBZR provides a reset signal to the host system when the monitored supply voltage drops below the threshold level. The reset output remains active until the supply voltage recovers and stabilizes above the threshold, plus a minimum hysteresis, ensuring a reliable reset operation. This reset delay prevents the system from restarting prematurely during transient conditions.

With a low quiescent current of typically 3 µA, the TLV803SDBZR is suitable for battery-powered devices where power conservation is critical. The device also features a wide operating temperature range from -40°C to +125°C, allowing it to function reliably in various environmental conditions.

The TLV803SDBZR is part of Texas Instruments' extensive voltage supervisor portfolio, which offers devices with different threshold voltages and reset timeout periods to accommodate a variety of application requirements. This voltage supervisor is an excellent choice for designers looking for a simple, effective way to enhance system reliability without increasing complexity or cost.
