General Description

The TPS2559 power-distribution switch is intended for applications where a low resistance, precision current limit switch is required or heavy capacitive loads are encountered.

The TPS2559 provides up to 5.5 A of continuous load current with a precise current limit set by a single resistor to ground.

Output current is maintained at a safe level by switching into a constant-current mode when the output load exceeds the current-limit threshold.

Key Features

Operating range: 2.5 V to 6.5 V.
Adjustable 1.2-A to 4.7-A I(LIMIT) (±4.4% at 4.7 A).
Short-circuit shutoff (typical): 3.5 µs.
High-side MOSFET: 13 mΩ.
Maximum standby supply current: 2 µA.
Built-in soft-start.
System-level ESD capable: 8 kV / 15 kV.
UL 2367 recognition pending 2.
