Analog Devices Inc./Maxim Integrated MAX6765EVKIT+

Overview

MAX6765EVKIT+ from Maxim Integrated is an evaluation kit for the MAX6765 automotive micropower linear regulator with supervisor functionality. It supports 4V–72V input, delivers up to 100mA output at fixed 5.0V (L/M suffix), features 31µA quiescent current, active-low open-drain/push-pull RESET, and 200ms fixed reset timeout - enabling rapid validation of always-on power-supply supervision in automotive control modules.

For engineers reviewing the MAX6765EVKIT+ datasheet, MAX6765EVKIT+ pinout, MAX6765EVKIT+ application, or MAX6765EVKIT+ equivalent, this kit provides full hardware reference design, test points for IN/OUT/ENABLE/RESET/TIMEOUT signals, thermal performance characterization under -40°C to +125°C conditions, and direct interface to µP watchdog and reset circuits per AEC-Q100-compliant automotive power architectures.

Technical Context

The MAX6765EVKIT+ implements the MAX6765TTL D4 variant: 5.0V fixed output, 4.625V RESET threshold (L option), and 200ms typical reset timeout (D4 option). It replicates the 6-pin TDFN-EP package layout with exposed pad thermal grounding and includes all required bypass capacitors (0.1µF on IN, 10µF on OUT), TIMEOUT-to-OUT connection for fixed timing, and ENABLE-controlled startup sequencing.

This kit validates critical automotive supervisory behaviors: brownout detection with guaranteed 75µs–200ms reset assertion hold time, dropout voltage ≤620mV at 100mA load, thermal shutdown at +160°C with 20°C hysteresis, and watchdog-free operation (as MAX6765 lacks WDI). It does not support adjustable output or HOLD/WDI functions - those require MAX6767/MAX6773 variants.

FAQ

What is the purpose of the MAX6765EVKIT+?

The MAX6765EVKIT+ is a fully assembled evaluation kit designed to accelerate development and validation of the MAX6765TTL D4 automotive linear regulator. It provides immediate access to all key signals (IN, OUT, ENABLE, RESET, TIMEOUT), pre-populated decoupling capacitors, thermal test points, and documentation for measuring quiescent current, dropout voltage, reset timing, and thermal shutdown behavior under real-world automotive conditions. The MAX6765EVKIT+ itself is not a production component but a design enablement tool for the MAX6765.

Which MAX6765 variant does the MAX6765EVKIT+ support?

The MAX6765EVKIT+ is configured for the MAX6765TTLD4 variant: 5.0V fixed output, L-grade 4.625V RESET threshold, and D4-coded 200ms typical reset timeout. It does not support other suffixes (e.g., MAX6765TTMD4 or MAX6765TTZD4) without hardware modification. The kit's PCB layout, component selection, and default jumpers are optimized exclusively for the TTLD4 configuration of the MAX6765.

Does the MAX6765EVKIT+ include watchdog timer functionality?

No. The MAX6765EVKIT+ evaluates the MAX6765 - a variant without watchdog timer (WDI) input. Watchdog functionality is only present in MAX6773/MAX6774 and MAX6773B/MAX6774B devices. The MAX6765EVKIT+ board has no WDI signal path, test point, or supporting circuitry; its RESET behavior is solely voltage-monitored and timeout-driven per the MAX6765's internal supervisor logic.

Can the MAX6765EVKIT+ be used to evaluate adjustable-output operation?

No. The MAX6765EVKIT+ is built for the fixed-output MAX6765TTL D4 and lacks SET pin routing, external resistor pads, or feedback divider components required for adjustable-mode operation (which begins with MAX6767). Its OUT pin is hardwired to the 5.0V preset configuration. To evaluate 1.8V–11V adjustable output, users must select the MAX6767EVKIT+ or MAX6773EVKIT+ instead.

Is the MAX6765EVKIT+ RoHS-compliant and AEC-Q100 qualified?

Yes. The MAX6765EVKIT+ contains the MAX6765TTLD4/V+ device, which carries the "/V+" suffix indicating AEC-Q100 qualification (Grade 0, -40°C to +125°C) and RoHS compliance ("+" denotes lead(Pb)-free packaging). The evaluation board itself uses RoHS-compliant assembly processes and materials, and its test reports include thermal cycling, humidity testing, and electrical validation aligned with automotive reliability standards.
