FEATURES
DESCRIPTION
The TPS22913 is a small, low rON load switch with
controlled turn on. The device contains a P-channel
MOSFET that can operate over an input voltage
range of 1.4 V to 5.5 V. The switch is controlled by an
on/off input (ON), which is capable of interfacing
directly with low-voltage control signals. The
TPS22913 is active high enable.

rON = 60-mΩ at VIN = 5-V
rON = 61-mΩ at VIN = 3.3-V
rON = 74-mΩ at VIN = 1.8-V
rON = 84-mΩ at VIN = 1.5-V
The TPS22913 contains
a 150-Ω on-chip load
resistor for quick output discharge when the switch is
turned off. The rise time of the device is internally
controlled in order to avoid inrush current. The
TPS22913 family has various slew rate options (see
Table 1).

Under-Voltage Lock Out
The TPS22913 device provides circuit breaker
functionality by latching off the power-switch during
reverse voltage situations. An internal reverse voltage
comparator disables the power-switch when the
output voltage is driven higher than the input (VIN) to
quickly (10µs typ) stop the flow of current towards the
input side of the switch. The reverse current
protection is active when the power switch is enabled
(ON). Additionally, during under-voltage lockout
(UVLO), or when the switch is disabled, no reverse
current can flow as the switch body diode is not
engaged.
