The MAX6365HKA29+ is a sensitive device and requires careful layout and placement to ensure optimal performance. It is recommended to place the device close to the battery, use short traces, and avoid routing high-frequency signals near the device. Additionally, a solid ground plane and a decoupling capacitor (e.g., 10uF) between VCC and GND are recommended.
The reset output (RST) is an open-drain output that requires an external pull-up resistor to a voltage rail (e.g., VCC). During power-up, the RST output is asserted low until the internal voltage regulator is stable and the device is fully powered up. During power-down, the RST output is asserted low to ensure a clean reset of the system. It is recommended to connect the RST output to the reset input of the microcontroller or other devices that require a reset signal.
The maximum current that can be drawn from the VCC output of the MAX6365HKA29+ is 150mA. However, it is recommended to limit the current to 100mA or less to ensure reliable operation and to prevent overheating of the device.
The reset threshold voltage (VTH) of the MAX6365HKA29+ is fixed at 2.92V. However, if a different reset threshold voltage is required, an external resistive divider network can be used to adjust the threshold voltage. The resistive divider network should be connected between the VCC output and the SENSE input, and the ratio of the resistors should be calculated based on the desired reset threshold voltage.
The SENSE input is used to monitor the voltage of the battery or power source. The SENSE input is connected to the positive terminal of the battery or power source, and the device compares the voltage at the SENSE input to the internal reset threshold voltage (VTH). If the voltage at the SENSE input falls below the reset threshold voltage, the device asserts the reset output (RST) low. The SENSE input can also be used to monitor the voltage of a secondary power source, such as a backup battery.
