The recommended layout and routing for the DS1233Z-15/T&R involves keeping the device as close as possible to the battery, using short and wide traces for the power lines, and avoiding routing signals under the device. Additionally, it's recommended to use a solid ground plane under the device to reduce noise and improve thermal performance.
To ensure the accuracy of the battery voltage monitoring function, it's essential to use a high-precision voltage reference, such as the internal reference of the DS1233Z-15/T&R, and to minimize the resistance of the voltage sense lines. Additionally, the device should be calibrated during manufacturing to account for any variations in the internal reference voltage.
The maximum allowed voltage on the VCC pin of the DS1233Z-15/T&R is 6V. Exceeding this voltage can cause permanent damage to the device. It's essential to ensure that the voltage on the VCC pin does not exceed 6V during operation, including during power-up and power-down sequences.
The reset pin (RST) of the DS1233Z-15/T&R should be pulled high during power-up and power-down sequences to ensure proper device operation. A pull-up resistor with a value of 1kΩ to 10kΩ is recommended to pull the RST pin high. Additionally, the RST pin should be decoupled from the system reset signal to prevent unwanted resets.
The typical current consumption of the DS1233Z-15/T&R during normal operation is around 15μA. However, this value can vary depending on the specific application and operating conditions. It's essential to consult the datasheet and application notes for more detailed information on power consumption.
