Input pin.
This pin is connected to a pull−down resistor internally, so that even when input wiring is
open−circuited, output can never be turned on inadvertently.
Output pin.
If an inrush current flows (e.g., from a lamp), the current is clamped at 10A (typ.) by an overcurrent
protective circuit. Also, a 150µs (typ.) mask circuit is included internally, so that if VDS ≥ 12V (typ.)
after this mask time, the current is clamped at 3A (typ.).
Ground pin.
