1.2 A Slew Rate Controlled Load Switch in PPAK SC75-6,
and TDFN4 1.2 mm x 1.6 mm
DESCRIPTION
The SiP4282 series is a slew rate controlled high side switch.
The switch is of a low ON resistance P-Channel MOSFET
that supports continuous current up to 1.2 A.
The SiP4282 series operates with an input voltage from
1.8 V to 5.5 V. It offers under voltage lock out that turns the
switch off when an input under voltage condition exists. The
"A" option without UVLO extends the minimum operation
voltage from 1.8 V down to 1.5 V. The SiP4282 is available in
two different versions of slew rates, 100 µs and 1 ms. The
SiP4282 series integrates load discharge circuit to ensure
the discharge of capacitive load when the switch is disabled.
The SiP4282 features low input logic level to interface with
low control voltage from microprocessors. This device has a
very low operating current (typically 2.5 µA for SiP4282 and
50 pA for SiP4282A).
The SiP4282 is available in lead (Pb)-free package options
including 6 pin PPAK SC75-6, and 4 pin TDFN4 1.2 mm x
1.6 mm DFN4 packages. The operation temperature range
is specified from - 40 °C to + 85 °C.
The SiP4282 compact package options, operation voltage
range, and low operating current make it a good fit for battery
power applications.
