Evaluation Module Overview
1 Evaluation Module Overview
1.1 Introduction
The BQ25750EVM evaluates for applications that use greater than a 100 W USB input with the new USB-C
Power Delivery (PD) Extended Power Range (EPR) and up to 13 cell Li-Ion battery charging implementing
CC/CV profile. Typical applications include medical equipment, solar backup chargers, energy storage systems,
drones, cordless power and garden tools.
This EVM does not include the EV2400 or USB2ANY interface device and does not provide any electrical
isolation for the digital interfaces.
BQ25750EVM and considering electrical safety is important when interfacing between the PC and EVM board.
When interfacing the EVM to the PC through the digital interfaces, digital isolators with isolation boundary is
recommended.
The BQ25750EVM does not have an isolation boundary and has smaller clearance and creep than normally
used on high-voltage boards. If the user applies high voltage to this board, all terminals are considered high
voltage and hazardous when live. Electric shock is possible when connecting the board to live wire. The board
must be handled by a professional with care. TI recommends the use of isolated test equipment with safety
protection features (such as overvoltage and overcurrent).

1.3 Device Information
The BQ25750EVM evaluation module (EVM) is an evaluation system for the BQ25750 IC. The BQ25750 IC is a
buck-boost battery charge controller with direct power path control. The BQ25750 has a wide input range of 4.2
V – 70 V, a wide output voltage range of up to 70 V, and bi-directional capabilities.
The device offers high-efficiency battery charging with accurate charge current and charge voltage regulation
over a wide voltage range. The design also includes automatic charge preconditioning, termination, and charge
status indication. The device integrates loop compensation for the buck-boost converter, which provides a
high-density design with ease of use. In reverse mode, the device draws power from the battery and regulates
the SYS terminal voltage.
The device supports stand-alone charging mode through resistor programmable limits in addition to the I2C
host-controlled charging mode. Input current, charge current, and charge voltage regulation targets are set
through the ILIM_HIZ, ICHG and FB pins, respectively.
