MAX6702ZKA+

Supervisors Overview

The MAX6702ZKA+ is a low-voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It features an 8-pin SOT-23 package and monitors three independent voltage inputs. The device provides an active-high, push-pull reset output with a fixed 200 ms reset delay time. It operates within a temperature range of -40°C to +125°C (TA). The component supports precision monitoring for standard supply voltages including +5.0V, +3.3V, +3.0V, and +2.5V.

Supervisors Feature Summary

• Monitors three independent voltage levels simultaneously
• Provides active-high reset output via push-pull configuration
• Includes manual reset capability and watchdog timer functionality

Supervisors Applications

• Multivoltage microprocessor supervision systems
• Precision monitoring of +5.0V, +3.3V, +3.0V, and +2.5V supply rails
• Low-voltage electronic circuits requiring power-fail detection

Supervisors Procurement Notes

Verify the specific suffix 'Z' against official Analog Devices documentation to confirm lead-free status and RoHS compliance details. Confirm availability status as distribution channels may vary. Ensure the ordering part number matches the exact pinout and electrical characteristics required for the design. Cross-reference datasheet revisions to ensure compatibility with current manufacturing standards.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage rails is required in a compact footprint. The active-high output and push-pull drive capability suit direct interfacing with logic inputs. Consider the wide operating temperature range for industrial or automotive environments. Verify that the fixed reset delay meets system timing requirements without external components.

Supervisors Part Context

The MAX6702 belongs to the MAX6701–MAX6708 family of supervisors designed for multivoltage applications. This family offers various pinout options to accommodate different supervision needs. The MAX6702 specifically targets scenarios requiring three-channel monitoring within a small SOT-23-8 package, providing a space-efficient solution for complex power management architectures.

Supervisors Replacement Considerations

The MAX6701–MAX6708 family shares similar functional architectures but varies in pinouts and channel counts. Verify pin-to-pin compatibility before substituting with other family members like the MAX6703 or MAX6704. Ensure the replacement part maintains the required active-high output polarity and three-input monitoring capability.
