TPS22968-Q1
SLVSCP7B – NOVEMBER 2014 – REVISED MARCH 2016
TPS22968x-Q1 5.5-V, 4-A, 27-mΩ On-Resistance Load Switch
1 Features
1 Integrated Dual Channel Load Switch
• Qualified for Automotive Applications:
– Device Temperature Grade 1 : –40°C to
+125°C Ambient Operating Temperature
Range
• Input Voltage Range: 0.8 to 5.5 V
• VBIAS Voltage Range: 2.5 to 5.5 V
• On-Resistance
– RON = 29 mat VIN = 5 V (VBIAS = 5 V)
– RON = 27 mat VIN = 3.3 V (VBIAS = 5 V)
– RON = 26 mat VIN = 1.8 V (VBIAS = 5 V)
• 4-A Maximum Continuous Switch Current per
Channel
• Low Quiescent Current
– 58-µA at VBIAS = 5 V (Both Channels)
• Low-Control Input-Threshold Enables Use of 1.2-,
1.8-, 2.5-, 3.3- V Logic
• Configurable Rise Time With CT Pin(1)
• Quick-Output Discharge (QOD)(2) (TPS22968-Q1
Only)
• 10-Pin WSON Package With Wettable Flanks
• ESD Performance Tested per JEDEC STD
– ±2-kV HBM and ±1-kV CDM
• Latch-Up Performance meets 100-mA per JESD
78, Class II
• GPIO Enable – Active High
(1) See Adjustable Rise Time for CT value versus rise time
(2) This feature discharges output of the switch to GND through a
270-Ω resistor, preventing the output from floating.
2 Applications
• Automotive Electronics
• Infotainment
• Cluster
• ADAS
3 Description
The TPS22968x-Q1 is a small, dual-channel load
switch with configurable rise time. The device
contains two N-channel MOSFETs that can operate
over an input voltage range of 0.8 V to 5.5 V and can
support a maximum continuous current of 4-A per
channel. Each switch is independently controlled by
an on/off input (ON1 and ON2), which is capable of
interfacing directly with low-voltage control signals.
The TPS22968-Q1 includes a 270 Ω on-chip resistor
for quick output discharge when the switch is turned
off.
The TPS22968x-Q1 is available in a small, space-
saving package (DMG) with wettable flanks and an
integrated thermal pad. The wettable flanks allow for
visual solder inspection. The device is characterized
for operation over the free-air temperature range of
–40 to +125°C.
