Qualified for automotive applications
AEC-Q100 qualified:
The TPS2295x-Q1 are small, single channel load
switches with controlled turn on. The devices contain
a N-channel MOSFET that can operate over an input
voltage range of 0.7 V to 5.7 V and can support a
maximum continuous current of 5 A.
– Device temperature grade 1: –40°C to 125°C
ambient operating temperature range
Integrated single channel load switch
Input voltage range: 0.7 V to 5.7 V
RON resistance
– RON = 14 mΩ at VIN = 5 V (VBIAS = 5 V)
5-A maximum continuous switch current
Adjustable Undervoltage Lockout Threshold
(UVLO)
•

•
The integrated adjustable Undervoltage Lockout
(UVLO) and adjustable Power Good (PG) threshold
provides voltage monitoring as well as robust power
sequencing. The adjustable rise time control of the
device greatly reduces inrush current for a wide
variety of bulk load capacitances, thereby reducing
or eliminating power supply droop. The switch is
independently controlled by an on and off input
(EN), which is capable of interfacing directly with
low-voltage control signals. A 15-Ω on-chip load is
integrated into the device for a quick discharge of the
output when the switch is disabled. The enhanced
Quick Output Discharge (QOD) remains active for a
short time after power is removed from the device to
finish discharging the output.

The TPS2295x-Q1 are available in small, space-
saving 10-SON packages with integrated thermal
pad, allowing for high power dissipation. The device
is characterized for operation over the free-air
temperature range of –40°C to +125°C.
