1.2 A Slew Rate Controlled Load Switch in PPAK SC75-6
DESCRIPTION
The SiP4282A is a P-Channel MOSFET power switch IC
designed for high-side load switching applications. The
output switching transistor is a P-Channel MOSFET device
that has a 140 mΩ RDS(ON) typically to increase load
switching power handling capacity. The SiP4282A is
available in two different versions with turn-on and turn-off
characteristics ranging from very fast to slew rate limited. In
addition to a fast turn-off time of 4 µs, the SiP4282A-3
version offers a shutdown load discharge circuit to
instantaneously turn off a load circuit when the switch is
disabled.
The SiP4282A load switch operates with an input voltage
ranging from 1.5 V to 5.5 V, making it ideal for both 3 V and
5 V systems. The SiP4282A also features an under-voltage
lock out which turns the switch off when an input
undervoltage condition exists. Input logic levels are TTL and
2.5 V to 5 V CMOS compatible. This device has a very low
operating current (typically 25 nA), making it ideal for battery-
powered applications. In shutdown mode, the supply current
de-creases to less than 1 µA.
The SiP4282A is available in a lead (Pb)-free 6 pin PPAK
SC75-6 package and is specified over - 40 °C to 85 °C
temperature range.
