description

The TPIC2404 is a monolithic high-voltage high-current quadruple low-side switch especially

designed for driving from low-level logic to peripheral loads such as relays, solenoids, motors, lamps, and other high-voltage high-current loads. The high-efficiency power switch is optimized for applications where a very rugged power switch is required. The device tolerates power supply transients and reverse battery conditions up to 13 V.

The TPIC2404 features four inverting open-collector outputs controlled by a common-enable input. When ENABLE is low, the outputs are disabled. An error-sensing circuit monitors load and device faults. When an error is sensed, the FAULT\ output goes to a low state. In addition, the device features on-board V_CC overvoltage and thermal overload protection circuits, and the outputs are current limit protected.
