Advance Information
Dual/Hex Low-Side Switch with
Both SPI and Parallel Input Control
The 33397 is a low-side switch that is user configurable to be either two
333 mΩ outputs (dual mode) or six 900 mΩ outputs (hex mode). Each output
is internally current limited and short-circuit protected. Output fault detection
capability includes “off state” open loads and “on state” short-to-battery
conditions. Faults for each output are latched into the fault register and serially
shifted out during serial communication.
