Monolithic Power Systems Inc. EVKT-MP2660

Overview

EVKT-MP2660 from Monolithic Power Systems is an evaluation kit for the MP2660 single-cell Li-ion/Li-polymer battery charger IC, featuring integrated power-path management, I²C programmability, and on-board hardware for real-time parameter tuning including charge voltage (4.200 V), charge current (8–535 mA), and input current limit (85–455 mA). It supports rapid validation of battery charging behavior in portable electronics design.

For engineers reviewing the EVKT-MP2660 datasheet, EVKT-MP2660 pinout, EVKT-MP2660 application, or EVKT-MP2660 equivalent, this kit enables hands-on configuration of MP2660 register settings-including thermal regulation, watchdog timer, BATT UVLO, and trickle charge-via MPS I²C GUI software under Windows XP/7+ with USB interface and ≥22.2 MB free space.

Technical Context

The EVKT-MP2660 comprises two hardware modules: the EV2660-C-01A evaluation board hosting the MP2660 IC with SYS/VIN/BATT/GND terminals and onboard passive components, and the EVKT-USBI2C-02 interface providing USB-to-I²C bridging using Silicon Labs CP2112 firmware. Communication operates at standard-mode I²C (100 kHz) with register read/write access to all configurable parameters.

Power delivery is decoupled across three domains: 4.6–5.5 V board supply, 3.9–7.0 V VIN input for charger operation, and 0–4.545 V battery voltage range. All I²C-modified settings are volatile and reset on power cycle; OTP programming requires external FAE support and produces a custom MP2660-xxxx variant.

Manufacturer

Monolithic Power Systems (MPS) is a fabless semiconductor company specializing in high-performance power management ICs, founded in 1997 and headquartered in Kirkland, Washington.

The MP2660 product line delivers highly integrated Li-ion battery chargers with system power-path control, targeting space-constrained, low-power portable applications where simultaneous system operation and battery charging are required.

FAQ

Does EVKT-MP2660 include the MP2660 IC pre-soldered on the board?

Yes. The EV2660-C-01A board includes the MP2660 IC mounted and fully populated with supporting passives, including input/output capacitors, current-sense resistors, and thermal pads. No assembly is required to begin evaluation.

Can I retain custom I²C register settings after power cycling the EVKT-MP2660?

No. All I²C-modified register values-including charge voltage, current limits, and timers-are volatile and revert to factory defaults upon power-down. Permanent configuration requires OTP programming through MPS FAE support and ordering a custom MP2660-xxxx variant.

What is the role of the EVKT-USBI2C-02 in this kit?

The EVKT-USBI2C-02 serves as a USB-to-I²C bridge using a Silicon Labs CP2112 controller. It enables bidirectional communication between the host PC and the MP2660 IC on the EV2660-C-01A board, allowing full register access without requiring external microcontrollers or logic analyzers.

Is thermal regulation adjustable via the GUI, and how does it behave during overtemperature events?

Yes. Thermal regulation threshold and recovery hysteresis are configurable via I²C registers. When die temperature exceeds the programmed limit, the MP2660 enters shutdown mode, halting charging and discharging until temperature falls below the hysteresis point, then automatically resumes operation.

What battery voltage range does the EVKT-MP2660 support during evaluation?

The kit supports battery voltages from 0 V to 4.545 V, matching the MP2660's specified BATT UVLO and regulation range. This allows safe testing with battery simulators, discharged cells, or partially charged Li-ion/Li-polymer sources without risk of reverse bias or overvoltage damage.
