DESCRIPTION

· The LM5060 is a high-side protection controller designed for intelligent control of a high-side N-channel MOSFET during normal on/off transitions and fault conditions.

· It controls in-rush current by maintaining a nearly constant rise time of the output voltage.

· Features a POWER GOOD output to indicate when the output voltage matches the input voltage and the MOSFET is fully on.

· Includes input UVLO with hysteresis and programmable input OVP for enhanced safety and control.

· An enable input allows for remote on/off control, and the programmable UVLO input can serve as a secondary enable for safety redundancy.

· A single capacitor programs the initial start-up VGS fault detection delay time, transition VDS fault detection delay time, and continuous over-current VDS fault detection delay time.

· In the event of a fault condition persisting beyond the allowed delay time, the MOSFET is latched off until the enable or UVLO input is toggled low and then high.

FEATURES

· Available in Automotive Grade / AEC Q-100.

· Wide operating input voltage range from 5.5V to 65V.

· Functional safety capable with documentation available to aid in functional safety system design.

· Less than 15-µA quiescent current in disabled mode.

· Controlled output rise time for safe connection of capacitive loads.

· Charge pump gate driver for external N-Channel MOSFET.

· Adjustable Undervoltage Lockout (UVLO) with hysteresis.

· UVLO serves as a second enable input for systems requiring safety redundancy.

· Programmable fault detection delay time.

· MOSFET latched off after load fault is detected.

· Active low open drain POWER GOOD (nPGD) output.

· Adjustable input Overvoltage Protection (OVP).

· Immediate restart after overvoltage shutdown.

· 10-Lead VSSOP package.

APPLICATIONS

· Automotive body electronics.

· Industrial power distribution and control.
