TPS3801J25DCKR Description

Short technical summary and product information.

The Texas Instruments TPS3801J25DCKR is an ultra-small supply voltage supervisor designed for applications requiring circuit initialization and timing supervision, particularly for DSPs and microprocessors. This device asserts a push-pull RESET signal when the supply voltage drops below a preset threshold of 2.25V. The RESET output remains asserted for a factory programmed delay time of 200ms after the voltage returns above the threshold.

 

Key features include a precision supply voltage monitor with a threshold accuracy of 2%, an active-low, push-pull reset output, and a manual reset input. The device operates over a temperature range of -40°C to +85°C and consumes a low supply current of 9mA. It is housed in a compact 5-pin SC-70 (SOT-323) package, making it suitable for space-constrained designs.

 

Applications for the TPS3801J25DCKR include systems using DSPs, microcontrollers, or microprocessors, wireless communication systems, portable and battery-powered equipment, programmable controls, intelligent instruments, industrial equipment, and notebook/desktop computers.
