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.
