Description
The SP2026-2EN is a dual +2.7V to +5.5V supervisory power control switch that is current limited to 1.25A and has thermal shutdown to protect itself and the load. It is compliant to USB specifications and has an input voltage range of +2.7V to +5.5V. The SP2026-2EN features two independent power switches and two error flag outputs. It has a 2.4V undervoltage lockout and a minimum continuous load current of 500mA per switch. The maximum on-resistance is 140mΩ and the on-state supply current is 100μA. Additionally, it has a shutdown current of 1μA and can be forced higher than the input in the off-state. The SP2026-2EN also has thermal shutdown protection and a 1ms soft-start power up. It is available in both active-high and active-low versions.
