Analog Devices Inc./Maxim Integrated MAX25210EVKIT#

Overview

MAX25210EVKIT# from Maxim Integrated is an evaluation kit designed to validate the MAX25210 ultra-low-quiescent-current, high-voltage linear regulator in automotive and battery-powered systems. It supports input voltages from 3.5V to 36V, delivers up to 300mA output current, consumes only 10μA quiescent current at no load, and features user-selectable fixed (3.3V/5V) or adjustable (0.6V–11V) output voltage configurations.

For engineers reviewing the MAX25210EVKIT# datasheet, MAX25210EVKIT# pinout, MAX25210EVKIT# application, or MAX25210EVKIT# equivalent, this kit enables rapid validation of LDO performance under cold-crank, load-dump (40V transient), and wide-temperature (−40°C to +125°C) conditions - critical for AEC-Q100-compliant automotive power design.

Technical Context

The MAX25210EVKIT# evaluates three package variants of the MAX25210 LDO: TDFN 3mm×3mm (U1), SO 5mm×4mm (U2), and TDFN 2mm×2mm (U3). Each variant shares identical electrical specifications including 280mV dropout at 200mA, open-drain active-low RESET with 93.5%/87.5% thresholds, and 60μs fixed reset delay extendable via external capacitor on TIMEOUT pin.

Hardware configuration is controlled by shunt jumpers (J1–J4, J13, J18, J23–J33) to select enable mode (EN tied to VIN or GND), output voltage mode (fixed or adjustable), and target package footprint. Dedicated SMB jacks provide isolated access to VIN, VOUT, RESET, and TIMEOUT signals for oscilloscope monitoring without probing solder pads.

FAQ

What does the MAX25210EVKIT# evaluate?

The MAX25210EVKIT# evaluates the MAX25210 family of ultra-low-quiescent-current linear regulators. It supports all three package variants - TDFN 3mm×3mm (U1), SO 5mm×4mm (U2), and TDFN 2mm×2mm (U3) - and enables full characterization of output regulation, RESET timing, enable control, thermal behavior, and transient response under automotive operating conditions. The MAX25210EVKIT# itself is not a production component but a fully assembled, tested PCB for engineering validation.

Can the MAX25210EVKIT# be used to test both fixed and adjustable output configurations?

Yes, the MAX25210EVKIT# supports both fixed and adjustable output modes via jumper configuration. For fixed 3.3V or 5V outputs, install shunts on J2/J4/J24 (pins 2–3) and J13/J18/J33 (pins 1–2 for 5V, pins 2–3 for 3.3V). For adjustable output (0.6V–11V), install shunts on J2/J4/J24 (pins 1–2) and remove shunts from J13/J18/J33, then set voltage using external 0402 resistors R3/R4, R5/R6, or R10/R11 per the provided divider equation. This flexibility is built into the MAX25210EVKIT# design.

Does the MAX25210EVKIT# include protection against load-dump transients?

Yes, the MAX25210EVKIT# evaluates the MAX25210's inherent 40V load-dump tolerance - a key feature verified per ISO 7637-2 Pulse 5a. The board routes input directly to the device's VIN pin without external TVS clamping, confirming that the MAX25210 itself sustains operation during 40V transients. This capability is integral to the MAX25210EVKIT#'s validation scope and eliminates need for add-on protection circuitry during testing.

How is the RESET signal configured and measured on the MAX25210EVKIT#?

The MAX25210EVKIT# provides direct access to the open-drain RESET output via dedicated SMB jack J11 and test pad. RESET asserts low when V_OUT falls below its threshold (93.5% or 87.5% of nominal) and deasserts after a fixed 60μs delay once V_OUT rises above threshold. Delay extension is supported by connecting a capacitor between TIMEOUT pin (J12) and GND - a feature validated on the MAX25210EVKIT# using standard 1000pF test capacitors.

Is the MAX25210EVKIT# compatible with standard lab equipment?

Yes, the MAX25210EVKIT# is designed for immediate use with common bench equipment: a 5V–40V/300mA DC power supply connects to VIN/GND terminals; passive or electronic loads interface via OUTPUT/GND pads; and a digital multimeter or oscilloscope connects to SMB jacks for VIN, VOUT, RESET, and TIMEOUT monitoring. All signal paths are impedance-matched (50Ω SMB) and routed with minimal stub length to preserve signal integrity during dynamic testing of the MAX25210.
