Description
The SLG59H1313C high-voltage load switch features a low 23mΩ RDSON internal nFET and protects low‑voltage 2.5Vdc to 5.5Vdc operating systems against voltage faults up to 29Vdc. An internal clamp circuit protects the downstream components from surge voltage up to 100V. The SLG59H1313C features a fast 50ns (typ.) overvoltage response time that turns off the internal nFET if the input voltage exceeds the OVP threshold. The OVP threshold is adjustable with optional external resistors to any voltage between 4V and 20V. Over‑temperature protection powers down the device at 145 °C (typ.). SLG59H1313C also features an overcurrent protection that turns off the switch if the current exceeds 7A (typ.), this gives additional protection from overheating the device. SLG59H1313C incorporates an open-drain output PG pin. When VIN_min < VIN < VOVLO and the switch is on, PG will be driven low indicating a good power input, otherwise, it is high impedance.
