Texas Instruments recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern around the device to ensure good heat dissipation. A minimum of 2 oz copper thickness is recommended for the top layer.
To ensure accurate current sensing, it's essential to follow the recommended layout guidelines, use a low-impedance current sense resistor, and minimize the distance between the sense resistor and the device. Additionally, consider using a Kelvin connection to the sense resistor to reduce errors.
Although the datasheet specifies a maximum VCC voltage of 5.5V, it's recommended to limit the voltage to 5V to ensure reliable operation and prevent damage to the device.
The POR and BOR features are designed to reset the device during power-up or brown-out conditions. To handle these features, ensure that your system design includes a suitable power-up sequence and a reset circuit that can handle the device's reset timing requirements.
While the datasheet specifies an operating temperature range of -40°C to 125°C, it's recommended to operate the device within a range of -20°C to 85°C for optimal performance and reliability.
