Maxim Integrated provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for high-frequency PCB design, such as using a solid ground plane, minimizing trace lengths, and using bypass capacitors to reduce noise and EMI.
The DS1845E-010/T&R can be programmed using the I2C interface. The device has a 7-bit address, and the output voltage can be set using the VOUT register. The output voltage range is 0.8V to 3.3V, and the resolution is 10mV. Refer to the datasheet for the complete programming guide.
The maximum output current capability of the DS1845E-010/T&R is 150mA. However, it's recommended to derate the output current based on the ambient temperature and the output voltage to ensure reliable operation.
The DS1845E-010/T&R has a built-in overcurrent protection (OCP) feature that limits the output current to 200mA. If the output current exceeds this limit, the device will enter a shutdown state to prevent damage. The OCP threshold can be adjusted using the OCP register.
The typical startup time for the DS1845E-010/T&R is 1ms. However, this time can vary depending on the output voltage, input voltage, and other factors. Refer to the datasheet for more information on startup time and power-up sequencing.
