EV6619L-Q-00A
2.5V to 28V, 5A, H-Bridge
Motor Driver Evaluation Board
DESCRIPTION
The EV6619L-Q-00A evaluation board is
designed to demonstrate the capabilities of the
MP6619L, an H-Bridge motor driver. It operates
from a supply input voltage (VIN) up to 28V, and
can deliver a motor current up to 5A. The
MP6619L is typically used to drive a brushed
DC motor.
The MP6619L has a configurable current limit
(ILIMIT). For simplicity, the output polarity can be
controlled by pulling the IN1 and IN2 pins high
or low.
Full protection features include over-current
protection (OCP), input over-voltage protection
(OVP), under-voltage lockout (UVLO), and
thermal shutdown. The input control signals for
the MP6619L are applied via the connector or
generated on the board.
The MP6619L is available in a QFN-19
(3mmx3mm) package. It is recommended to
read the MP6619L datasheet prior to making
any changes to the EV6619L-Q-00A.

QUICK START GUIDE
1. Connect the input voltage (2.5V ≤ VIN ≤ 28V) and input ground to the VIN and GND connectors,
respectively.
2. Connect the VCC voltage (2.8V ≤ VCC ≤ 5.5V) and ground to the VCC and GND connectors,
respectively.
3. Connect the VDD voltage (3.3V or 5V) and ground to the VDD and GND connectors, respectively.
4. Set the input control and logic signal through the CN1 connector via the external MCU, or manually
through SW1. Manual action requires an external 3.3V or 5V VDD as a pull-up power supply.
Table 1 shows the logic truth table.

5. The current control trip value is set by the adjustable resistor (R4). When the ISET pin is floating,
the current trip voltage (VITRIP) is set to the default (200mV). If a resistor is connected between ISET
and GND, then VITRIP can be reduced below 200mV to reduce power loss on the sense resistor. The
relationship between VITRIP and the ISET resistor (RISET) can be calculated with Equation (1):
VITRIP (V) 0.2

6. The output current limit (IOUT_LIM) is determined by VITRIP and RISEN. If RISET is connected between
ISET and ground, then IOUT_LIM can be estimated with Equation (2):
IOUT_LIM (A) 0.2

RISET kΩ RISEN Ω

If ISET remains floating, then IOUT_LIM can be calculated with Equation (3):
