The TPIC2404 is a monolithic high-voltage
The tab is electrically connected to the GND pins.
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.
