Monolithic Power Systems Inc. EV2602-Q-00B

Overview

EV2602-Q-00B from Monolithic Power Systems is a fully assembled and tested evaluation board for the MP2602DQ linear single-cell Li-ion battery charger IC, supporting 5V input, 0.8A programmable charge current, 4.2V CV threshold, and integrated thermal protection and battery temperature monitoring - used to validate charging behavior in portable consumer electronics.

For engineers reviewing the EV2602-Q-00B datasheet, EV2602-Q-00B pinout, EV2602-Q-00B application, or EV2602-Q-00B equivalent, this board enables rapid validation of CC/CV charge profiles, adapter power-good signaling, charge status indication, and 28V surge tolerance in real-world USB/adapter-powered systems.

Technical Context

The EV2602-Q-00B implements the MP2602DQ's full functional interface: it routes VIN (5V), BAT, GND, and CHG_OK/PGOOD signals to accessible test points and headers; supports jumper-selectable charge currents (200mA–1A); and uses discrete resistors (R5, R6–R8) to set battery full threshold (IFB) and thermal regulation parameters.

Board-level design includes reverse-current blocking via internal MOSFET control, trickle-charge enablement at low battery voltage, and dual LED indicators (green = input present, red = charging active), all directly driven by MP2602DQ's open-drain outputs without external logic.

FAQ

What input voltage range does the EV2602-Q-00B support?

The board is designed for 5 V nominal input, matching standard USB and adapter sources. Its underlying MP2602DQ IC integrates proprietary over-voltage protection that withstands transient surges up to 28 V without damage or latch-up - verified per MPS datasheet Rev. 1.0.

How is charge current configured on this evaluation board?

Charge current is set using three 2-pin jumpers (JP1, JP2, JP3) in binary combination: positions marked "X" establish connections to select 200 mA, 500 mA, 700 mA, 800 mA, or 1000 mA - full table provided in the Quick Start Guide on page 5 of the official documentation.

Does the board provide battery temperature monitoring capability?

Yes - the MP2602DQ IC monitors battery temperature via an external NTC thermistor connected to the TS pin. The EV2602-Q-00B includes dedicated test points and routing for TS signal access, enabling real-time thermal profiling during charge cycle validation.

Can the EV2602-Q-00B operate without a battery connected?

Yes - the board powers its LEDs and maintains VIN detection functionality even with no battery. However, the MP2602DQ enters standby mode and disables charging circuitry when BAT is open; CHG_OK remains inactive until a valid battery is detected and voltage rises above trickle-charge threshold.

What is the purpose of JP4 on the board?

JP4 is a 3-pin header that selects the power source for the status LEDs: position 1–2 powers LEDs from VIN (input side), position 2–3 powers them from BAT (battery side). This allows visibility of charge status whether the input is present, absent, or the battery is sustaining load independently.

Is the EV2602-Q-00B RoHS-compliant and lead-free?

Yes - the board uses RoHS-compliant components and lead-free solder per MPS manufacturing standards. All listed BOM parts (e.g., Murata GRM32ER71H475KA88L, Panasonic ERJ-3EKF series resistors, LNJ306G5URA LED) are documented as lead-free and RoHS-6 compliant in their respective manufacturer datasheets.
