Adjustable Current-Limit, 100 mA–1100 mA
Fast Overcurrent Response - 2 S Typical
The
TPS2550/51
power-distribution
switch
is
intended for applications where heavy capacitive
85-m High-Side MOSFET (DBV Package)
loads and short-circuits are likely to be encountered,
Reverse Input-Output Voltage Protection
incorporating a 100-m
, N-channel MOSFET in a
Operating Range: 2.5 V to 6.5 V
single package. The current-limit threshold is user
adjustable between 100 mA and 1.1 A via an external
Deglitched Fault Report
resistor. The power-switch rise and fall times are
1-A Maximum Standby Supply Current
controlled
to
minimize
current
surges
during
Junction Temperature Range: –40°C to 125°C
switching.
Built-in Soft-Start
The device limits the output current to a desired level
15 kV ESD Protection (with external
by switching into a constant-current mode when the
capacitance)
output load exceeds the current-limit threshold or a
short is present. An internal reverse-voltage detection
UL Listed – File No. E169910
comparator disables the power-switch in the event
Current-Limit Resistor Calculator – SLVC163
that the output voltage is driven higher than the input
to protect devices on the input side of the switch. The
FAULT
logic
output
asserts

both
overcurrent and reverse-voltage conditions.
