HFET1™ High-Voltage Integrated Power Control Switch

A Surge-protected, 28-V Tolerant USB Type C Power Splitter/Switch in 28L WLCSP

The SLG59H1302C is a 130-V surge-protected, 28-V tolerant power splitter with two high-current switches and an 0.1 A capable LDO in 28-ball WLCSP. With independent control for each channel, the SLG59H1302C contains a 6 A capable, 12 mΩ nFET switch for the BUS-to-OUT path and a reverse-blocking 6 A capable, 24 mΩ nFET switch for the BUS-to-SYS path. An internal, “always ON” LDO is 0.1 A capable and can be used to supply power to downstream devices when the BUS terminal voltage is higher than 2.7 V. When the SYS terminal turns on, the IC’s push-pull PG output becomes asserted. The SLG59H1302C is fully specified over the industrial -40°C to 85°C temperature range.
