DS1706PESA Equivalent & Substitute Parts

Part Overview

The DS1706PESA is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) device. This single-channel supervisor provides push-pull, totem pole output with active high reset functionality, designed for power-on reset and simple reset applications. The DS1706PESA is currently listed as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs requiring similar supervisory capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1706PESA is determined by the following critical parameters:

• Package Compatibility: All substitute parts must use 8-SOIC (0.154", 3.90mm Width) surface mount packaging to ensure PCB layout compatibility without redesign.
• Functional Type: All substitutes must be single-channel supervisors with simple reset/power-on reset functionality.
• Voltage Threshold: The 2.63V threshold is the primary electrical specification for substitution eligibility.
• Operating Temperature Range: All substitutes must support -40°C ~ 85°C operating temperature.
• Reset Logic and Output Configuration: Substitutes must maintain compatible reset polarity and output drive characteristics for circuit integration.

The substitute parts identified below meet these core substitution criteria. Variations in reset timeout (130ms vs. 140ms) and reset logic polarity (active high vs. active low) represent functional differences that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

DS1706PESA+ (Analog Devices Inc./Maxim Integrated)

The DS1706PESA+ is the direct successor to the DS1706PESA, maintaining identical electrical specifications including 2.63V threshold, active high reset logic, and 130ms minimum reset timeout. This part is currently in active production status and is ROHS3 compliant, making it the preferred replacement for applications requiring exact functional equivalence. The DS1706PESA+ is available in tube packaging with substantial inventory.

STM706PM6F (STMicroelectronics)

The STM706PM6F provides functional equivalence with identical voltage threshold, output configuration, and reset polarity. The reset timeout specification is 140ms minimum, representing a 10ms increase from the original part. This part is active and ROHS3 compliant, supplied in tape and reel packaging. Selection of this part requires confirmation that the extended reset timeout does not impact system timing requirements.

MIC706PMY and MIC706PMY-TR (Microchip Technology)

Both Microchip variants (tube and tape & reel packaging) share the 2.63V threshold and 8-SOIC package with the original part. These parts differ in reset logic polarity (active low versus active high) and do not specify output configuration. These differences require circuit-level evaluation to determine compatibility with existing reset signal conditioning and downstream logic. Both parts are active and ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can DS1706PESA+ be used as a direct replacement for DS1706PESA?

A: Yes. The DS1706PESA+ maintains identical electrical specifications, package, and mounting type. The primary difference is product status (active versus obsolete) and improved RoHS compliance.

Q: What is the impact of the 140ms reset timeout in STM706PM6F compared to the 130ms specification of DS1706PESA?

A: The STM706PM6F provides a 10ms longer minimum reset timeout. Applications with timing-critical reset sequencing must evaluate whether this extended delay affects system initialization behavior or meets minimum hold-time requirements for downstream logic.

Q: Why do MIC706PMY and MIC706PMY-TR specify active low reset logic instead of active high?

A: Reset logic polarity is a functional characteristic that determines whether the reset output is asserted high or low. Microchip's MIC706 series uses active low reset logic, requiring different circuit integration compared to the active high logic of the original DS1706PESA. Circuit redesign or signal inversion may be necessary.

Q: Are all substitute parts available in the same packaging options?

A: No. DS1706PESA+ is available in tube packaging. STM706PM6F is supplied in tape and reel. MIC706PMY is available in tube, while MIC706PMY-TR is supplied in tape and reel. Packaging selection depends on assembly process requirements and volume considerations.

Q: Do all substitute parts meet RoHS compliance requirements?

A: The original DS1706PESA is RoHS non-compliant. All identified substitutes (DS1706PESA+, STM706PM6F, MIC706PMY, MIC706PMY-TR) are ROHS3 compliant, meeting current environmental and regulatory standards.

Q: What is the moisture sensitivity level for these supervisor ICs?

A: All parts, including the original DS1706PESA and all substitutes, have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
