Detailed Description

High-voltage hot swap controller for negative rails (ideal for -48V systems). Operates from -80V to -9V. Uses an external N-channel MOSFET to control inrush current and protect the load from faults. Latched-fault version (-1) turns off and stays off after a fault until reset. Compact 10-VSSOP package. Programmable thresholds and timing for UVLO, OVP, current limit, circuit breaker, and fault timeout. One channel. Low supply current (typ ~2 mA). Industrial temperature range -40°C to 125°C. RoHS3 compliant and lead-free (NOPB).

Key Features

Supply voltage range: -80V to -9V (negative input rail)

Application focus: -48V telecom/industrial backplanes

Fault response: Latched off on fault (LM5067-1 variant)

External switch: Drives an external N-channel MOSFET (no internal pass FET)

Programmable protections: UVLO, OVP, current limit, circuit breaker, fault timeout

Inrush control: Soft-start/ramp via external components for controlled plug-in

Channels: 1

Quiescent current: ~2 mA

Operating temperature: -40°C to 125°C

Package: 10-VSSOP (also referenced as 10-TFSOP / 10-MSOP, 3.00 mm width)

Mounting: Surface mount

Compliance: RoHS3, lead-free (NOPB finish)

Base product number: LM5067

Key Advantages

Protects sensitive boards during hot-plug into -48V backplanes

Prevents overloads and short circuits with fast fault detection and precise current limit

Reduces downtime and damage costs with reliable latched fault action

Simplifies design with easy, resistor/capacitor-set thresholds and timers

Small footprint saves board space while managing high-voltage rails

Wide operating range covers telecom-grade negative supply distributions

Stable performance over industrial temperature range

Works with a broad choice of external MOSFETs to optimize RDS(on) and SOA for your load

Packaging

Shipment format: Tape & Reel (TR) for automated assembly

Device package/case: 10-VSSOP (also called 10-TFSOP / 10-MSOP), approx. 3.00 mm body width, low-profile molded epoxy package, lead-free matte-tin leads

Pin configuration: 10-lead format with typical pins for gate drive, current sense, UVLO/OVLO dividers, timer/fault, enable, and status (see datasheet for exact pinout)

Mounting: Surface-mount footprint compatible with standard VSSOP land patterns

Thermal characteristics: Small-outline package; follow good PCB copper area and thermal relief practices to manage dissipation (consult datasheet thermal guidance)

Electrical properties summary: Negative supply operation (-80V to -9V), ~2 mA supply current, single-channel controller, external MOSFET gate control, programmable protection network
