LP5309

32V Tolerance Over-Voltage Protection Switch with

Programmable Over-Current Protection

Features

General Description

⚫

Input voltage tolerance up to 32V

The LP5309 is a power switch device provides full

protection to systems and loads which may encounter

large current and input over-voltage conditions.

Low on-state resistance to 145mΩ

90μA low current consumption

Integrated OCP at 2.5A (Typical)

Under-voltage lockout: 2.7V

Over-voltage protection: 6V

Output discharge integrated

Thermal shutdown protection

ESD Protection:

The device contains a 145mΩ MOSFET which can

operate over an input voltage range from 3.0V to 32V. The

OVP will disconnect VIN and VOUT when the voltage on

VIN is higher than over voltage threshold. The over-current

protection could be settable using an external resistor.

When the current reaches the threshold, the device will

turn off the power FET to prohibit excessive currents from

causing damage. Switch is controlled by an active-low

logic pin. Thermal shutdown protection is integrated which

shuts off the switch to prevent damage to the part when

the temperature is higher than threshold.

Human Body Model: 4kV

Charged Device Model: 0.5kV
