Monolithic Power Systems Inc. EV2662-C-01A

Overview

EV2662-C-01A from Monolithic Power Systems is an evaluation board for the MP2662 linear battery charger IC, designed to validate power path management, I²C-programmable charging parameters (e.g., 500mA input current limit, 4.200V battery regulation), and <1μA battery leakage in single-cell Li-ion systems. It supports simultaneous system powering and battery charging from USB or AC adapter inputs.

For engineers reviewing the EV2662-C-01A datasheet, EV2662-C-01A pinout, EV2662-C-01A application, or EV2662-C-01A equivalent, this board enables rapid validation of MP2662-based charging architectures in space-constrained wearable and smart handheld designs with programmable safety thresholds and real-time status reporting via I²C.

Technical Context

The EV2662-C-01A implements full functional validation of the MP2662's autonomous charge algorithm-including pre-charge (3.0V threshold), constant-current fast charge (8–456mA), and constant-voltage regulation (3.6–4.545V, ±0.5% accuracy)-with independent system load and battery power paths.

It integrates hardware-level protections: input overvoltage clamp (21V max), battery UVLO (2.4–3.03V programmable), discharge current limiting (400–3200mA), thermal shutdown, and NTC/PCB OTP monitoring-all configurable and reportable via its on-board I²C interface connected to U1 (MP2662GC-0000 in WLCSP-9).

FAQ

What software is required to configure the EV2662-C-01A?

The MP2662 Evaluation Kit software (Windows XP/7 compatible EXE) is mandatory. It communicates via the EVKT-USBI2C-02 adapter to read/write I²C registers, adjust charge parameters like input current limit (50–500mA), battery UVLO (2.4–3.03V), and termination current (1–31mA), and monitor real-time status flags including thermal faults and battery disconnect events.

Does the EV2662-C-01A support battery temperature monitoring?

Yes-it supports NTC-based battery temperature sensing via dedicated RT1/RT2 resistor positions (10kΩ default). The board's configuration allows enabling PCB-level OTP or external NTC monitoring through register-controlled function selection, as defined in Table 2 of the reference document.

Can the EV2662-C-01A operate without the USB-to-I²C kit?

No-the I²C interface is not exposed via jumpers or test points for direct MCU access. Configuration and status monitoring require the EVKT-USBI2C-02 communication kit and the official MP2662 Evaluation Kit software; no standalone analog or GPIO-based control is implemented on the board.

What is the default battery regulation voltage and how is it set?

The default battery regulation voltage is 4.200 V, factory-programmed into the MP2662GC-0000 IC. It is adjustable between 3.6 V and 4.545 V via I²C register write (REG0x02[15:0]), with ±0.5% accuracy maintained across temperature and load conditions per the MP2662 datasheet specification.

Is the EV2662-C-01A RoHS-compliant and lead-free?

Yes-both the EV2662-C-01A board and its populated MP2662GC-0000 IC are lead-free, halogen-free, and fully compliant with the EU RoHS directive. MPS confirms green status on its official Quality Assurance webpage, and all passive components (e.g., GRM188R61E475KE11D) meet the same environmental standards.

What protection features are hardware-implemented versus register-configurable?

Hardware protections include input overvoltage clamp (21V absolute max), battery UVLO cutoff, and thermal shutdown. Register-configurable features include charge termination current (1–31mA), auto-recharge delta (100/200mV), safety timer duration, I²C watchdog timeout, and NTC/PCB OTP enablement-each mapped to specific MP2662 control registers per the official register map.
