DS1832U Equivalent & Substitute Parts

Part Overview

The DS1832U is a single-channel power supply supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, part of the MicroMonitor™ series. This device provides push-pull reset output with programmable voltage threshold monitoring and active high/active low reset capability. The DS1832U is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations. The primary substitute maintains functional equivalence while offering improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1832U is determined by strict equivalence across the following critical parameters:

• Voltage Monitoring Capability: Single-channel monitoring at identical threshold levels (2.55V, 2.88V)
• Output Configuration: Push-pull output topology
• Reset Logic Levels: Active high/active low capability
• Reset Timeout Duration: 250ms minimum specification
• Operating Temperature Range: -40°C to 85°C
• Package Compatibility: 8-TSSOP/8-MSOP form factor with 0.118" width
• Electrical Characteristics: Identical functional behavior within specified parameters

The DS1832U+ qualifies as a direct substitute based on complete parameter alignment across all monitored electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The DS1832U+ is the direct equivalent substitute for the DS1832U. Both parts maintain identical electrical specifications and package compatibility. The DS1832U+ offers two significant advantages:

Product Status: The DS1832U+ carries Active product status, ensuring continued manufacturer support, availability, and technical documentation access. The DS1832U is classified as Obsolete, limiting future sourcing options and support.

Regulatory Compliance: The DS1832U+ is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The DS1832U is RoHS non-compliant, which may present compliance challenges in applications subject to RoHS regulations.

Both parts maintain identical REACH status (REACH Unaffected) and ECCN classification (EAR99). Pin-for-pin compatibility and functional equivalence are confirmed across all monitored parameters.

Frequently Asked Questions (FAQ)

Q: Are DS1832U and DS1832U+ pin-for-pin compatible?

A: Yes. Both parts use the 8-TSSOP/8-MSOP package with identical 0.118" width and 8-uMAX/uSOP supplier device package designation. No PCB layout modifications are required for substitution.

Q: What are the voltage threshold options for these supervisors?

A: Both the DS1832U and DS1832U+ support two voltage threshold levels: 2.55V and 2.88V. Threshold selection is determined by part number suffix or internal configuration.

Q: Can these parts be used in applications requiring RoHS compliance?

A: The DS1832U+ is ROHS3 compliant and suitable for RoHS-regulated applications. The DS1832U is RoHS non-compliant and should not be used in new designs subject to RoHS requirements.

Q: What is the reset timeout specification?

A: Both parts specify a 250ms minimum reset timeout, ensuring adequate system stabilization time following power-on or voltage threshold detection events.

Q: Are there differences in operating temperature ranges?

A: No. Both the DS1832U and DS1832U+ operate across the identical temperature range of -40°C to 85°C (TA).

Q: What packaging options are available?

A: The DS1832U+ is supplied in Tube packaging. The DS1832U packaging format is not specified in available documentation. Both parts use the same 8-TSSOP/8-MSOP physical package.

Q: Can these supervisors monitor multiple supply voltages?

A: No. Both the DS1832U and DS1832U+ are single-channel supervisors, monitoring one voltage supply. For multi-channel applications, alternative MicroMonitor™ series devices with multiple monitoring channels are required.
