The TMUX7462F is a four-channel protector that can be placed on the front end of a signal path to protect sensitive components downstream from damage caused by overvoltage faults. Each of the 4 channels has an internal switch that is turned-off automatically upon occurrence of an overvoltage fault without the need of external controls. This simplifies robust system level protection designs by removing the need for control signals for each channel of the device. The overvoltage protection is available in powered and powered-off conditions, making the TMUX7462F suitable for applications where power supply sequencing cannot be precisely controlled.

The switch channels remain in the high impedance state (regardless of switch input conditions) when the devices power supplies are floating, grounded, or at a level that is below the undervoltage (UV) threshold. If the signal level on any Sx pin exceeds the fault supply (V FP or V FN) by a threshold voltage (V T), then the Sx pin becomes high impedance and an output fault flag is asserted low to indicate a fault condition under normal operation. The drain pin (Dx) is either pulled to the fault supply voltage that was exceeded or left floating depending on the DR control logic.

The device operates with dual supplies (±5 V to ±22 V), a single supply (8 V to 44 V), or asymmetric supplies. The low and flat on-resistance of the device makes the TMUX7462F an excellent solution for data acquisition applications where excellent linearity and low distortion is critical.
