MAX6833HXRD0+

Supervisors Overview

The MAX6833HXRD0+ is an ultra-low-voltage voltage supervisor manufactured by Maxim Integrated, now part of Analog Devices Inc. This fixed-threshold device operates within a supply voltage range of 750mV to 3.6V and features a reset threshold voltage of 1.2V. It provides one channel of supervision in a compact SC-70 (SOT-323) three-terminal package. The component is lead-free, RoHS compliant, and designed for operation across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low minimum operating supply voltage enabling functionality in battery-powered systems
• Fixed reset threshold voltage ensuring precise power monitoring without external adjustment
• Compact surface-mount packaging suitable for space-constrained portable designs

Supervisors Applications

• Portable consumer electronics requiring low standby current
• Battery-operated devices with minimal voltage headroom
• Embedded systems needing reliable power-on reset signals

Supervisors Procurement Notes

Verify the manufacturer designation as Maxim Integrated or Analog Devices Inc. on the datasheet and ordering information. Confirm the package type is SC-70/SOT-323 and the reset threshold is fixed at 1.2V. Ensure compliance with RoHS and lead-free requirements matches project specifications. Cross-reference the full part number MAX6833HXRD0+ to avoid confusion with similar variants.

Supervisors Selection Notes

Select this component when the system voltage drops below 1.2V but remains above 750mV during normal operation. It is suitable for applications where a fixed reset point is acceptable and adjustable thresholds are unnecessary. Consider the SC-70 footprint if board space is limited. Verify that the 1.2V threshold aligns with the microcontroller or logic circuit reset requirements.

Supervisors Part Context

The MAX6833 belongs to Maxim’s family of ultra-low-voltage supervisors designed for modern low-power applications. Unlike standard supervisors requiring higher voltages, this series supports operation down to 750mV. The HX suffix indicates a specific threshold version, while RD0 denotes the SC-70 package and tape-and-reel delivery format.
