Design PC power systems that are space conscious and thermally efficient
PC and notebook designs require efficient power and battery management. With low quiescent currents, our load switches take only a minimal percentage of power budgets, while bringing necessary protection features to downstream systems.
Benefits:
- Protections such as inrush current control and short-circuit and reverse current protection.
- A thermal shutdown feature to give a heat-conscious solution.
- Small and compact packaging – less than 5 mm2.
