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 VCC overvoltage and thermal overload protection circuits, and the outputs are current limit protected.

NOTES: 1. 2. 3. 4. All voltage values are with respect to network GND. For a fault condition to be valid, the output voltage needs to be a minimum of 7 V. Output sink current is limited by the overcurrent limit. For operation above 25C free-air or case temperature, refer to Figures 1 and 2. To avoid exceeding the design maximum virtual junction temperature, these ratings should not be exceeded. Due to variations in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection can be activated at power levels slightly above or below rated dissipation.
