DESCRIPTION
The SP2026 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. 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, V
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 , and
supplies a 500mA minimum output current per switch. In overcurrent and thermal shutdown,
error flags may be asserted for overtemperature.
