MAX821SUS-T Frequently Asked Questions (FAQ)
-
The MAX821SUS-T is a sensitive device and requires careful layout and placement to ensure proper operation. It is recommended to follow the layout guidelines provided in the datasheet, including keeping the device away from high-current carrying traces, using a solid ground plane, and minimizing the distance between the device and the battery.
-
The MAX821SUS-T has a specific startup sequence that must be followed to ensure proper operation. The device should be powered up in the following order: VCC, EN, and then BAT. The EN pin should be held low during power-up to prevent the device from turning on prematurely.
-
The maximum voltage rating for the BAT pin is 6.5V. Exceeding this voltage can cause damage to the device. It is recommended to use a voltage regulator or other protection circuitry to ensure that the voltage on the BAT pin does not exceed the maximum rating.
-
The UVLO threshold can be adjusted by connecting a resistor divider network between the VCC pin and the UVLO pin. The resistor values can be calculated using the formula provided in the datasheet. It is recommended to use a 1% tolerance resistor to ensure accurate threshold setting.
-
The EN pin is an active-low enable input that allows the device to be turned on and off. When the EN pin is low, the device is enabled and will regulate the output voltage. When the EN pin is high, the device is disabled and the output voltage will be turned off. The EN pin can be used to implement power-saving modes or to turn off the device during shutdown.
