The MAX1946ETA+ requires careful layout and placement to ensure proper operation. Maxim recommends placing the device close to the battery, using short traces, and separating the analog and digital grounds. A 4-layer PCB with a solid ground plane is recommended. Refer to the Maxim application note AN4387 for detailed layout guidelines.
The MAX1946ETA+ requires external components such as resistors, capacitors, and inductors. The selection of these components depends on the specific application and battery type. Refer to the Maxim datasheet and application notes for guidance on component selection and calculation formulas.
The MAX1946ETA+ has a maximum input voltage rating of 28V. However, the device can withstand up to 30V for short durations (less than 100ms). It's essential to ensure that the input voltage does not exceed 28V for reliable operation.
The MAX1946ETA+ has a built-in OVP feature that can be enabled by connecting the OVP pin to a resistor divider network. The OVP threshold can be set by selecting the appropriate resistor values. Refer to the Maxim datasheet and application notes for detailed implementation guidelines.
The EN (enable) pin is used to turn the MAX1946ETA+ on or off. When the EN pin is high, the device is enabled, and when it's low, the device is disabled. The EN pin can be connected to a logic signal or a push-button switch to control the device's operation.
