Analog Devices Inc./Maxim Integrated MAX14750EVKIT#

Overview

MAX14750EVKIT# from Analog Devices is an evaluation kit designed to accelerate development and validation of the MAX14750 companion power-management IC for rechargeable battery systems. It provides full access to all 25-bump WLP signals, supports I²C configuration, enables real-time monitoring of buck-boost (2.5–5V), buck (1.0–2.0V), LDO (0.9–4.0V), and load-switch functions, and facilitates battery impedance measurement and sequencing control in wearable medical and fitness devices.

For engineers reviewing the MAX14750EVKIT# datasheet, MAX14750EVKIT# pinout, MAX14750EVKIT# application, or MAX14750EVKIT# equivalent, this kit delivers verified reference schematics, layout files, firmware examples, and test points for validating quiescent current (≤8.3 µA), switch on-resistance (≤250 mΩ), and regulator transient response under real-world load steps - critical for ultra-low-power portable medical design.

Technical Context

The MAX14750EVKIT# implements a complete hardware platform for the MAX14750 IC, featuring direct pin control of each regulator and switch via dedicated enable inputs (HVEN, SWEN, LEN, BEN), I²C interface (SDA/SCL), and monitor multiplexer (MON) for voltage sensing across HVOUT, BOUT, LOUT, SWOUT, BIN, and LIN. It supports configurable soft-start, UVLO thresholds, and battery-impedance measurement sequences per the MAX14750's register map.

Designed for evaluation of the 2.26mm × 2.14mm 25-bump WLP device, the kit includes decoupling capacitors matching datasheet recommendations (e.g., 10µF at HVOUT/BOUT, 100µF at SWOUT), test points for all critical nodes, and jumper-selectable VCC supply paths to isolate regulator inputs during characterization - enabling accurate measurement of micro-IQ performance (1.1 µA buck-boost, 0.9 µA buck, 0.9 µA LDO).

FAQ

What is the primary purpose of the MAX14750EVKIT#?

The MAX14750EVKIT# is an evaluation kit for the MAX14750 companion power-management IC. It enables engineers to configure, characterize, and validate the device's buck-boost, buck, LDO, and load-switch functions - including sequencing, I²C control, and battery impedance measurement - before integrating into final designs such as wearable medical monitors.

Does the MAX14750EVKIT# support both MAX14720 and MAX14750 ICs?

No. The MAX14750EVKIT# is specifically designed for the MAX14750 IC and leverages its individual enable-pin architecture (HVEN, SWEN, LEN, BEN). While the MAX14720 shares the same WLP package and core regulators, it uses sequencer-based control and button monitoring not implemented on this kit - use MAX14720EVKIT# for that device.

Can the MAX14750EVKIT# be used to measure battery impedance?

No. Battery impedance measurement is only supported on the MAX14720 (with BatZUVLO enabled). The MAX14750EVKIT# does not implement the required SWIN-to-VCC connection scheme or sequencing logic for impedance detection - this function is excluded from the MAX14750's feature set per the datasheet.

What supply voltages does the MAX14750EVKIT# accept for testing the MAX14750?

The MAX14750EVKIT# accepts input voltages from 1.8V to 5.5V on VCC, BIN, LIN, and HVIN rails - matching the absolute maximum ratings and operating ranges specified for the MAX14750. Jumper options allow independent biasing of each rail to validate UVLO behavior and cross-regulator interaction.

Is firmware or software provided with the MAX14750EVKIT#?

Yes. Analog Devices provides the MAX14750EVKIT# with GUI-based configuration software, register map documentation, Python scripts for I²C read/write, and example firmware for Arduino-compatible hosts - all accessible via the official Analog Devices website and included in the kit's digital resource bundle.
