Method and system for switching between a totem-pole drive mode and an open-drain drive mode |
摘要 |
An output driver that may be configured to operate as a totem-pole driver, or as an open-drain driver. The output driver comprises a totem-pole driver coupled to an output pin. A control circuit is coupled to the output enable input of the totem-pole driver. The control circuit is supplied with an open-drain control signal controlled by the user interface. When the open-drain control signal is at a first logic level, the output driver operates as an open-drain driver. When the open-drain control signal is at a second logic level, the output driver is configured to operate as a totem-pole driver.
