Thermal Protection
During output short circuit conditions, the LM3355 will draw
high currents causing a rise in the junction temperature.
On-chip thermal protection circuitry disables the charge

thermal trip point, and re-enables the charge pump when the
junction temperature falls back to a safe operating point.
