PT8A2766JTAEX

PT8A2766JTAEX is a kind of power distribution switch, load driver produced by Power-One. It utilizes a ring-type push-pull output stage for controlling analog and digital loads in a wide range of applications, from consumer audio and communications, to industrial and automotive systems.

PT8A2766JTAEX has two over-current protection circuits that automatically shut off the output MOSFETs, which provides instantaneous fault protection against short-circuits and over-current events. The device also features under-voltage lock-out (UVLO) to prevent enable pulse or logic input glitches, as well as protection against reverse battery conditions. It allows operation of the load at high efficiency over a wide input supply range.

This device operates in either the PUSH-PULL or PULL-UP configuration depending upon the logic state of the EN pin. In the PUSH-PULL configuration, the HS and LS pins form the power switch outputs, while in PULL-UP configuration the HS and EN pins are connected together with the LS pin acting as the power switch output.

PT8A2766JTAEX is widely used in consumer audio and motor control applications as well as PLCs, communication hubs and LED drivers. It also provides many control functions such as short turn-OFF delay, short turn-ON delay and soft turn-ON, which allow the user to control the loading conditions of detecting circuits. It also allows the user to optimize the performance in terms of power savings. In addition, the device includes built-in hysteresis to reduce the inrush current.

The working principle of PT8A2766JTAEX is based on the push-pull output stage. When the EN pin is low, the HS and LS pins are initially forced high. When the EN pin is transitioned high, the HS and LS pins then transition low. When the EN pin is forced low, the HS and LS pins are then forced high, thus turning the output off.

The device also features a 2-wire interface on the HS and LS pins, which supports parallel and master-slave configurations, and is compliant with the venerable PCA9536 I2C bus-addressable control scheme. Additionally, it supports user selectable input/output delay control options as well as adjustable slew rate control options. This allows the user to fine-tune the device for optimal performance.

In summary, PT8A2766JTAEX is a kind of power distribution switch, load driver produced by Power-One. It is widely used in consumer audio and motor control applications, as well as PLCs and communication hubs. Its working principle is based on the push-pull output stage, and it supports user selectable input/output delay control options as well as adjustable slew rate control options. It provides many control functions such as short turn-OFF delay, short turn-ON delay and soft turn-ON, which allows the user to optimize performance in terms of power savings.
