Latch-Off on Fault (-1) and Retry (-2) Versions
The TPS2421 has multiple programmable protection

limit, and a fault timer. The current dual thresholds
allow the system to draw short high current pulses,
while the fault timer is running, without causing a

Hotswap MOSFET protection is provided by power
limit circuitry which protects the internal MOSFET
against SOA related failures.
The TPS2421 is available in latch-off on fault (-1) and
retry on fault (-2).
