SGM2541
28V/16V Bidirectional Load Switch
with Wireless/Dual Input Capability
GENERAL DESCRIPTION
FEATURES
The SGM2541 bidirectional load switch is designed for
systems or chargers with high voltage quick charging
capability and wireless charging capability. The device
supports up to 20V operating input voltage (28V
withstand) at USBIN pins, and provides input
voltage-clamped protection for input surge events up to
130V. The device can also provide 16V reverse voltage
at the OUT pins.
● Bidirectional Switch for USBIN and OUT to Allow
On-The-Go (OTG) Mode
● Input Voltage Range:
3V to 20V at USBIN and 3V to 16V at OUT
● Programmable OVP Threshold Voltages
● 28V Tolerance on USBIN Pin
● 130V Surge Protection
● 5A Continuous Current from USBIN to OUT
● 5A Continuous Current from OUT to USBIN in
OTG Mode
The two OVP threshold voltages (17V/13V) can be
programmed through VP pin. The over-voltage
protection function can ensure the safe operation of
surge events in any state.
● Low On-Resistance: 29mΩ (TYP)
● 1.4V Control Logic
● Soft-Start to Reduce Input Peak Current
● Available in a Green WLCSP-2.43×1.75-20B Package
● -40℃ to +85℃ Operating Temperature Range
The addition of a wireless Rx with an enable/disable pin
allows the load switch to implement an equivalent 2:1
power multiplexer (PMUX).
The bidirectional device can detect and support
USB-OTG applications. It also includes under-voltage
lockout, over-voltage lockout and over-temperature
protection circuits designed to automatically isolate the
power switch terminals when a fault condition occurs.
APPLICATIONS
Smart Phone
Tablet PC
Mobile Devices with Wireless Charging Options
The SGM2541 is available in a Green WLCSP-2.43×
1.75-20B package. It operates over an ambient
temperature range of -40℃ to +85℃.

ESD Susceptibility
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
