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
IN
= 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
, and
supplies a 500mA minimum output current per switch. In overcurrent and thermal shutdown,
error flags may be asserted for overtemperature.
