MAX802LCPA Equivalent & Substitute Parts

Part Overview

The MAX802LCPA is a Power Management Integrated Circuit (PMIC) supervisor with push-pull, totem pole output configuration. It monitors a single voltage channel with a 4.65V threshold and provides active-low reset functionality with a 140ms minimum timeout. The device is packaged in an 8-DIP through-hole format and operates across the 0°C to 70°C temperature range.

The MAX802LCPA is classified as obsolete. Identifying equivalent and substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Engineering Selection Recommendations

For Direct Replacement (Push-Pull Output Required):

MAX690ACPA+, MAX694CPA+, and MAX703CPA+ are active products from Analog Devices Inc./Maxim Integrated that provide identical electrical specifications to the MAX802LCPA. All three are ROHS3 compliant and operate within the 0°C to 70°C temperature range. These parts are suitable for applications requiring push-pull, totem pole output configuration with 140ms reset timeout and 4.65V threshold monitoring.

For Extended Temperature Range Applications:

ADM690AANZ provides push-pull output with identical reset timeout (140ms) and voltage threshold, but extends the operating temperature range to -40°C to 85°C. This part is ROHS3 compliant and suitable for industrial or automotive environments requiring wider temperature operation.

For Alternative Output Configurations:

LTC690CN8#PBF and LTC694CN8#PBF offer open drain or open collector output instead of push-pull configuration. These parts are suitable only when the circuit design accommodates open drain output topology. LTC694CN8#PBF maintains the 140ms reset timeout matching the MAX802LCPA timing specification.

For Extended Temperature with Alternative Output:

LTC690IN8#PBF and LTC694IN8#PBF extend the operating temperature range to -40°C to 85°C with open drain output configuration. These parts are appropriate for designs that require both wider temperature operation and open drain output topology.

Compliance Considerations:

The MAX802LCPA is RoHS non-compliant. All active substitute parts listed (MAX690ACPA+, MAX694CPA+, MAX703CPA+, ADM690AANZ, ADM690ANZ, LTC690CN8#PBF, LTC690IN8#PBF, LTC694CN8#PBF, LTC694IN8#PBF) are ROHS3 compliant, supporting modern procurement and environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX690ACPA+ be used as a direct replacement for MAX802LCPA?

A: Yes. MAX690ACPA+ matches all critical parameters: 4.65V voltage threshold, push-pull totem pole output, active-low reset logic, 140ms reset timeout, 8-DIP package, and 0°C to 70°C operating temperature. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between push-pull and open drain output configurations?

A: Push-pull output (MAX802LCPA, MAX690ACPA+, MAX694CPA+, MAX703CPA+, ADM690AANZ, ADM690ANZ) actively drives the output high and low. Open drain output (LTC690CN8#PBF, LTC690IN8#PBF, LTC694CN8#PBF, LTC694IN8#PBF) can only pull the output low; the high state requires an external pull-up resistor. Circuit design must accommodate the output configuration type.

Q: Can I use ADM690ANZ instead of MAX802LCPA?

A: ADM690ANZ is not a direct substitute. While it provides push-pull output, 4.65V threshold, and active-low reset, its reset timeout is 35ms minimum, not 140ms. Use only if the application circuit can tolerate faster reset timing.

Q: Are all substitute parts available in 8-DIP through-hole packaging?

A: Yes. All listed substitute parts are packaged in 8-DIP (0.300", 7.62mm) with through-hole mounting type, ensuring mechanical and electrical compatibility with MAX802LCPA PCB layouts.

Q: What is the advantage of extended temperature range parts like LTC690IN8#PBF?

A: Extended temperature range parts (-40°C to 85°C) operate across wider environmental conditions compared to the MAX802LCPA (0°C to 70°C). These are suitable for industrial, automotive, or outdoor applications. However, LTC690IN8#PBF uses open drain output, requiring circuit design accommodation.

Q: Why do some parts have different reset timeout values?

A: Reset timeout is a timing-critical parameter that determines how long the supervisor holds the reset signal active after power supply stabilization. MAX802LCPA specifies 140ms minimum. Parts with 35ms timeout (ADM690ANZ, LTC690CN8#PBF, LTC690IN8#PBF) reset faster and are suitable only for applications that do not require extended reset duration.

Q: Is MAX802LCPA+ the same as MAX802LCPA?

A: MAX802LCPA+ is functionally identical to MAX802LCPA with two differences: tube packaging (vs. unspecified packaging) and ROHS3 compliance (vs. RoHS non-compliant). All electrical specifications and performance characteristics are identical.
