TPS370533D Description

Short technical summary and product information.

The Texas Instruments TPS370533D is part of the TPS370x-xx family of microprocessor supply voltage supervisors. These ICs are crucial for ensuring proper system initialization and timing supervision, particularly in DSP and processor-based applications.

The TPS370533D offers a power-on reset generator with a fixed delay time of 200 ms, eliminating the need for external capacitors. It includes precision supply voltage monitoring for levels such as 2.5 V, 3 V, 3.3 V, and 5 V, along with a voltage monitor for power-fail or low-battery warnings. The integrated watchdog timer (specific to TPS3705-xx models) adds an extra layer of system reliability.

This device operates within a temperature range of -40°C to 85°C and has a maximum supply current of 50 µA. It is available in an 8-pin SOIC package, making it suitable for various board designs. The reset output is active-low and push-pull, and the reset threshold accuracy is 1.9%.

Designed for robustness, the TPS370533D supports a VCC range from 2 V to 6 V. Its pin-for-pin compatibility with the Maxim MAX705 through MAX708 series simplifies migration and design choices.
