Transistors - FETs, MOSFETs - ArraysAO8804 is a single-output low side load switch with two enable pins. It operates over an input voltage range of 6-30V and is functional over a wide temperature range of -40℃ to +125℃. This device has a 3A current limit rating and can withstand up to +60V on the output. AO8804 integrates two level-shifted PMOS, two low threshold N-Channel MOS, a logic level converter and an output driver. AO8804\'s main application field is board level power management in computing, microcontroller, and industrial control applications. It can be used to provide power supply control, power sequencing and fault protection in data processing and sensing systems. This device is also suitable for applications such as motor control and automotive systems, where it can be used for H-bridge high side/low side gate drive and regulated gate drive delivery. AO8804 features a unique two-enable structure, which is useful for independent control of two output supplies. One enable is used to turn the device on or off, while the other can be used to provide sequencing or fault protection in microcontroller and data processing applications. AO8804 integrates level-shifted power MOSFETs to reduce power dissipation and increase efficiency.AO8804 also has an integrated logic level converter and a CMOS output driver, which can drive up to 3A loads. The output driver ensures that the output signal is correctly routed even with irregular pulse patterns. The logic level converter can detect logic signal levels from an input voltage range of 2V to 6V and then drive the MOS switches and output driver at voltages up to +60V. AO8804 also features ESD protection and over temperature protection. AO8804 works by driving two integrated N-Channel MOSFETs with the two enable pins. The enable pins can be configured for active high or active low, as required. When the first enable pin is low, the PMOS will conduct current from the VIN to ground and the N-Channel MOSFETs will be turned off. When the first enable pin is high, the PMOS will be turned off and the two N-Channel MOSFETs will be activated, allowing current to pass through the device.When the second enable pin is low, both of the MOSFETs will be turned off and current will not flow through the device. When the second enable pin is high, the MOSFETs will remain activated and current will flow through the device. The logic level converter and output driver are used to ensure that the output voltage is correctly driven even with irregular pulse patterns. In conclusion, AO8804 is a single-output low side load switch with two enable pins. It is commonly used for board level power management and can be used for H-bridge high side/low side gate drive and regulated gate drive delivery. AO8804 integrates a logic level converter, two low threshold N-Channel MOSFETs, two level-shifted PMOS, and a CMOS output driver. It offers ESD protection, over temperature protection, and a 3A current limit rating for increased reliability.
