MAX16058ATA26+

Supervisors Overview

The MAX16058ATA26+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.1 V to 5.5 V and features a fixed reset threshold of 2.625 V. The device draws a typical quiescent current of 125 nA, ensuring minimal power consumption. It provides an active-low, open-drain output with a manual reset input and includes a watchdog timer function. The reset delay time is specified at 14.18 ms, with an accuracy of 2.5%. It is housed in an 8-pin TDFN package and supports operation from -40°C to +125°C.

Supervisors Feature Summary

• Ultra-low 125 nA quiescent current for battery-powered applications
• Integrated watchdog timer with manual reset capability
• Capacitor-adjustable reset delay for flexible timing control
• High-accuracy 2.5% threshold monitoring

Supervisors Applications

• Portable consumer electronics requiring low standby power
• Battery-operated medical devices
• Industrial control systems with watchdog requirements
• Automotive infotainment subsystems

Supervisors Procurement Notes

Verify the specific suffix '26' indicates the 2.625 V threshold variant during procurement. Confirm RoHS compliance status through official manufacturer documentation. Ensure the 8-TDFN package dimensions match your PCB footprint design. Check for any obsolescence notices or lifecycle changes directly from Analog Devices before finalizing orders.

Supervisors Selection Notes

Select this component when a fixed 2.625 V monitoring level is required alongside watchdog functionality. The 125 nA current draw makes it suitable for energy-constrained designs compared to higher-current supervisors. Consider the 14.18 ms default delay and capacitor adjustability for system startup stability. Verify that the open-drain output interface is compatible with the downstream logic levels.

Supervisors Part Context

The MAX16058 belongs to Maxim's nanopower supervisory family, designed for critical voltage monitoring in space-constrained applications. It integrates essential protection features like watchdog and manual reset into a compact 8-TDFN package. This series targets industries demanding high reliability and low power consumption, such as automotive and industrial sectors.

Supervisors Replacement Considerations

Cross-reference with other MAX16058 variants (e.g., ATA16+, ATA17+) if different threshold voltages are acceptable. Ensure pinout compatibility when substituting with similar 8-pin supervisor ICs from other manufacturers.
