condition.
Power-Up and Sleep Mode
[Control Register Address Range A4h:8Ch, B8h]
The MAX24001 can be put into a low-power mode of operation when the SLEEP pin is asserted. This is achieved
by combining the sleep function with the chip-power sequencing, SLEEP can be configured to independently affect
the Rx and Tx signal paths.
Rx Signal path: The response to the SLEEP pin is controlled by the rx_respond_to_sleeppin register.
Tx Signal path: The response to the SLEEP pin is controlled by the tx_respond_to_sleeppin register.
Figure 23. Conditions for Moving In and Out of Sleep Mode
The device will only move between these states when power sequencing is enabled (tx_powerup_en and
rx_powerup_en are set).
The host can alternatively put the MAX24001 to sleep using the tx_force_sleep and rx_force_sleep registers.
