Monolithic Power Systems Inc. EV6515-F-00A

Overview

EV6515-F-00A from Monolithic Power Systems is an evaluation board for the MP6515 H-bridge motor driver IC, supporting 5.4–35V input voltage and delivering up to 2A continuous motor current. It features internal current sense output, fault indication (nFAULT), and dual logic supply compatibility (3.3V/5V) for MCU interface in brushed DC motor control applications.

For engineers reviewing the EV6515-F-00A datasheet, EV6515-F-00A pinout, EV6515-F-00A application, or EV6515-F-00A equivalent, this board enables rapid validation of MP6515's PWM-driven H-bridge operation, thermal performance under 2A load, OCP/OVP/OTP protection behavior, and VISEN-based current monitoring calibration using the onboard RV1 potentiometer.

Technical Context

The EV6515-F-00A implements a complete test platform for the MP6515 TSSOP-16 EP H-bridge driver, with dedicated connectors for VIN (5.4–35V), motor outputs (OUT1/OUT2), logic inputs (ENBL/BMODE/PHASE), and analog feedback (VISEN). All protection functions - over-current (OCP), over-voltage (OVP), and over-temperature (OTP) - are fully wired and observable via nFAULT pin.

It supports both microcontroller-driven control (via 10-pin CN1 header) and manual evaluation (via 8-bit DIP switch SW1), with configurable braking modes (synchronous fast decay), forward/reverse direction control, and adjustable current-sense gain through RV1 (10kΩ trimmer) scaling the VISEN output voltage proportional to motor current.

FAQ

What input voltage range does the EV6515-F-00A support?

The board accepts 5.4V to 35V DC input on the VIN connector, directly powering the MP6515's internal regulators and gate drivers. Operation below 5.4V disables the device; exceeding 35V risks permanent damage to the MP6515 IC and bypass capacitors C1–C4.

How is motor current measured on this evaluation board?

Motor current is sensed internally by the MP6515 and output as a scaled analog voltage on the VISEN pin. The onboard RV1 (10kΩ trimmer) adjusts the gain, enabling calibration to match external ADC reference voltages - typical scaling is 200mV/A or 500mV/A depending on RV1 setting.

Can the EV6515-F-00A be used with 3.3V microcontrollers?

Yes - the board's logic interface (CN1 and SW1) is compatible with both 3.3V and 5V CMOS signaling. Input thresholds are designed per MP6515 specifications: VIH ≥ 2.0V (3.3V systems) and VIH ≥ 3.5V (5V systems), ensuring reliable ENBL/BMODE/PHASE signal interpretation.

What protection features are implemented and how are they indicated?

OCP, OVP, and OTP are fully implemented using MP6515's internal circuits. Fault conditions assert the nFAULT pin low; the board routes this signal to CN1 Pin 9 and provides a dedicated test point. No external components are required to activate or monitor these protections.

Does the board support synchronous rectification or fast decay braking?

Yes - the MP6515 supports synchronous fast decay during brake states, controlled via BMODE and PHASE inputs. The truth table in the Quick Start Guide defines all four operating modes (forward, reverse, brake-low, brake-high), and the board's layout preserves full switching integrity for <100ns dead-time-sensitive timing.

Is thermal management provided for extended 2A operation?

The board uses 2oz copper layers, thermal vias under the MP6515's exposed pad (TSSOP-16 EP), and strategic copper pours on both sides. At 2A continuous load and 25°C ambient, measured junction temperature rise is ≤35°C - sufficient for unforced-air bench use but requires heatsinking for sustained >60°C ambient operation.
