Descripción general

Description

Introduction to LTC4219IDHC-12
- The LTC4219 is a high-side hot-swap controller that drives an external MOSFET to safely connect/disconnect a supply rail (typical in 12V backplanes or cards).
- It providing controlled inrush, current limit, and fault protection to protect both the power source and downstream circuitry.
Key features (typical):
- Programmable current limit and soft-start for inrush control
- Overcurrent protection with latch and status indication
- Overvoltage/undervoltage protection
- Thermal/overtemperature protection
- Optional reverse-current protection and fault logic
Applications:
- Hot-swap or ORing on 12V rails in servers, telecom/datacom gear, storage, and backplane applications
Package/abbreviation:
- LTC4219IDHC-12 denotes the 12-lead package variant and its temperature/leadframe grade as defined by the datasheet (pinout and ratings vary by package). Check the datasheet for exact details.
For exact specs, pinout, and circuit examples, refer to the LTC4219IDHC-12 datasheet.

Features

Key features of LTC4219IDHC-12:
- Hot-swap controller with gate drive for external N-channel MOSFETs
- Adjustable current limit via sense resistor
- Soft-start / controlled inrush current
- Input undervoltage and overvoltage protection (UVLO with hysteresis)
- Overcurrent protection (short-circuit) with latch or hiccup behavior
- Overtemperature protection with latch
- Reverse-battery and reverse-current protection
- Fault and Power-Good/Status signaling outputs
- Wide input voltage range suitable for multi-rail power systems
- Compact package (IDHC) for small-footprint designs
Note: For exact electrical specs and pinout details, please refer to the LTC4219IDHC-12 datasheet.

Package

The LTC4219IDHC-12 uses a 12‑lead DHC package, i.e., a 12‑pin thin small‑outline (TSSOP‑12) style package.

Pinout

- Pin count: 12 pins
- Function: LTC4219IDHC-12 is a hot-swap controller with surge/overcurrent protection for a power rail. It drives an external MOSFET to limit inrush current and protect the supply from faults (includes overcurrent/overvoltage protection and fault/status signaling).

Manufacturer
