ADJUSTABLE CURRENT-LIMITED POWER-DISTRIBUTION SWITCHES Adjustable Current-Limit, 100 mA–1100 mA Fast Overcurrent Response-2 μS
Typical The TPS2550/51 power-distribution switch is
intended for applications where heavy capacitive•
85-mΩ High-Side MOSFET (DBV Package) loads and short-circuits are likelyto be encountered,•
Reverse Input-Output Voltage Protection incorporatinga 100-mΩ, N-channel MOSFETina•
Operating Range: 2.5Vto 6.5V single package. The current-limit thresholdis user
adjustable between 100 mA and 1.1A via an external•
Deglitched Fault Report resistor. The power-switch rise and fall times are•
1-μA Maximum Standby Supply Current controlled to minimize current surges during•
Junction Temperature Range: –40°Cto 125°C switching.
Built-in Soft-Start The device limits the output current•
15 kV ESD Protection (with external by switching intoa constant-current
capacitance) output load exceeds the current-limit
shortis present. reverse-voltage
