SiP32510
Vishay Siliconix
1.2 V to 5.5 V, Slew Rate Controlled Load Switch in TSOT23-6
DESCRIPTION
SiP32510 is a slew rate controlled load switches designed for
1.2 V to 5.5 V operation.
The switch element is of n-channel device that provides low
RON of 44 m typically over a wide range of input.
SiP32510 has low switch on-resistance starting at 1.5 V input
supply. It features a controlled soft on slew rate of typical
1.6 ms that limits the inrush current for designs of heavy
capacitive load and minimizes the resulting voltage droop at
the power rails. With a typical turn on delay of 0.4 ms, the
total turn on time is typically 2 ms.
The SiP32510 features a low voltage control logic interface
(On/Off interface) that can interface with low voltage control
signals without extra level shifting circuit.
The SiP32510 has exceptionally low shutdown current and
provides reverse blocking to prevent high current flowing into
the power source.
SiP32510 integrates a switch OFF output discharge circuit.
SiP32510 is available in TSOT23-6 package.

Pulse Current Capability
The device is mounted on the evaluation board shown in the
PCB layout section. It is loaded with pulses of 5 A and 1 ms
for periods of 4.6 ms.
5A
1 ms
180 mA
4.6 ms
The SiP32510 can safely support 5 A pulse current
repetitively at 25 °C.
Switch Non-Repetitive Pulsed Current
The SiP32510 can withstand inrush current of up to 12 A for
100 µs at 25 °C when heavy capacitive loads are connected
and the part is already enabled.
Recommended Board Layout
For the best performance, all traces should be as short as
possible to minimize the inductance and parasitic effects.
The input and output capacitors should be kept as close
as possible to the input and output pins respectively.
Connecting the central exposed pad to GND, using wide
traces for input, output, and GND help reducing the case to
ambient thermal impedance.

RDS(ON) Measurement
As mentioned in the thermal consideration section, the
RDS(ON) is an important specification for the load switch. A
proper method to measure the RDS(ON) will ensure the
proper calculation of the maximum operating power the
SiP32510 load switch. The Kelvin connection directly to the
input/output pin of the device is used to measure the dropout
voltage of the SiP32510. By using the Kelvin connection to
measure the dropout voltage will eliminate the measurement
error due to the voltage drop caused by the forced power
current. As illustrated in the following layout, J6 (OUT-S) is
Kelvin connection to the output of SiP32510 and J5 (IN-S) is
the Kelvin connection to the input of SiP32510. A current
meter is used to measure the output current.
RDS(ON) is calculated by the following formula:
Dropout Voltage
RDS(on) = Output Current
