Monolithic Power Systems Inc. EV6606-F-00A

Overview

EV6606-F-00A from Monolithic Power Systems is an evaluation board designed to demonstrate the MP6606 8-channel low-side driver IC with serial interface, integrated LS-FETs and HS clamp diodes for inductive load control, supporting up to 60V supply voltage, 750mA per channel output current, and 3.3V/5V logic interface - used for unipolar stepper motor and solenoid driving in industrial automation systems.

For engineers reviewing the EV6606-F-00A datasheet, EV6606-F-00A pinout, EV6606-F-00A application, or EV6606-F-00A equivalent, this board enables rapid validation of SPI-controlled low-side switching performance, fault response (OCP/UVLO/OT), latch-synchronized multi-device operation, and thermal behavior under 750mA inductive loads at up to 60V.

Technical Context

The EV6606-F-00A implements a complete test platform for the MP6606 GF-grade IC in TSSOP-20EP package, featuring on-board TVS protection (SMAJ24A), configurable LATCH routing via P3 jumper or S2 dial switch, and dual power domains (VIN up to 60V, VCC at 3.3V/5V). It supports both direct VIN-to-VCLAMP connection and external TVS-based clamping.

SPI interface signals (SDI, SDO, SCLK) are routed to P2 header with 5×2 pinout; output channels OUT1–OUT8 terminate to 1mm SIP headers; fault status is indicated by LED1 driven by nFAULT. The board includes bulk (C1), ceramic decoupling (C5–C8), and current-sense-ready layout for dynamic load testing.

FAQ

What power supply configurations does the EV6606-F-00A support?

The board supports two VIN configurations: (1) direct VCLAMP-to-VIN tie for 4.5V–60V operation, or (2) 24V TVS diode between VIN and VCLAMP for 4.5V–30V operation. VCC must be set to 3.3V or 5V using external supply connected to dedicated terminals.

How is the LATCH signal controlled on this evaluation board?

LATCH can be configured either via jumper JP1 on P3 to tie it to SCS (SPI chip select), or independently controlled using the S2 4-bit DIP switch. This enables synchronization of data latching across multiple MP6606 devices in daisy-chained systems.

Does the EV6606-F-00A include protection circuitry for the MP6606 IC?

Yes - the board integrates SMAJ24A TVS diodes (D1, D2, D3) on VIN, VCLAMP, and ENBL lines; bulk electrolytic (C1) and ceramic (C5–C8) capacitors for transient suppression and decoupling; and LED1-driven nFAULT monitoring for real-time OCP, UVLO, and OT fault detection.

Can the EV6606-F-00A drive inductive loads directly?

Yes - each of the eight OUTx terminals connects directly to the MP6606's low-side MOSFET outputs and supports up to 750mA continuous current into inductive loads (e.g., solenoids, stepper coil segments), with integrated HS clamp diodes providing flyback path when VCLAMP is properly biased.

Is GUI software provided for configuring the MP6606 via this board?

Yes - MPS provides a dedicated GUI application that communicates over SPI to configure output states, set delay timing between byte transfers, and monitor receive buffer contents. The GUI supports single-send and loop-send modes, with real-time feedback via nFAULT and LED1.

What is the purpose of the P1 header on the EV6606-F-00A?

P1 is a 10-pin 2.54mm SIP header providing access to all eight OUTx outputs plus ENBL, nFAULT, and GND - enabling direct connection to external test fixtures, custom load boards, or measurement equipment without soldering to individual 1mm SIP terminals.
