The recommended layout and routing for the DS14287 involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the device and the battery. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure accurate temperature measurement with the DS14287, it's essential to follow proper PCB layout and routing guidelines, use a thermally conductive material for the PCB, and ensure good thermal contact between the device and the PCB. Additionally, calibration of the device may be necessary to achieve high accuracy.
The maximum allowed voltage on the VCC pin of the DS14287 is 5.5V. Exceeding this voltage can cause permanent damage to the device.
The power-on reset (POR) of the DS14287 can be handled by adding a capacitor between the VCC pin and the GND pin. The value of the capacitor depends on the specific application and the desired POR time. A typical value is 10nF to 100nF.
Yes, the DS14287 is suitable for use in battery-powered devices due to its low power consumption and ability to operate from a single lithium-ion cell. However, it's essential to consider the device's power consumption and the battery's capacity to ensure the desired battery life.
