Dual-channel high-side switch with fixed current limiting
The TPS2003CDRCR integrates two N-channel high-side power switches with a 1:2 input-to-output ratio, meaning a single enable signal controls both outputs simultaneously. Fault protection is comprehensive: fixed current limiting, over-temperature shutdown, reverse-current blocking, and under-voltage lockout (UVLO) on the input rail. The status flag output asserts low when any fault condition is active.
Sourcing and compliance status
