A device is disabled in thermal shutdown until the excessive current load is removed, the appropriate enable pins are toggled, or the die temperature cools to 120 °C. The undervoltage lockout feature disables the output switches until a valid input voltage, VIN = 2.4V, is present. Once a valid input voltage is present and the SP2026 is enabled, a 1ms soft start prevents momentary voltage drops caused by charging a capacitive load. The SP2026 has a low on resistance, 100m Ω, and supplies a 500mA minimum output current per switch. In overcurrent and thermal shutdown, error flags may be asserted for overtemperature. +2.7V to +5.5V USB Power Control Switch ® s 100 µA On-State Supply Current s 1 µA Shutdown Current s Output Can Be Forced Higher Than Input (Off-State) s Thermal Shutdown s 1ms Soft-Start Power Up s Active-High Version: SP2026-1 s Active-Low Version: SP2026-2 ENA GND OUTA FLGA FLGB OUTB IN ENB 8 7 4 3 2 1 5 6 SP2026 ® ® |
