Mingjiada Electronics Supply ADI LTC4217 And LTC4224 Series Hot Swap Controllers

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of [ADI] LTC4217 and LTC4224 hot-swap controllers, designed to meet the hot-swap protection and power management requirements of servers, storage systems, communications, industrial control and multi-rail power supply systems.

[ADI] LTC4217 — 2A Integrated Hot-Swap Controller
1. Overview: The LTC4217 is an integrated solution for hot-swap applications, enabling circuit boards to be safely inserted into and removed from a live backplane. The device integrates a hot-swap controller, a power MOSFET and a current-sensing resistor into a single package to meet the requirements of miniaturised applications.
The LTC4217 provides independent inrush current control, as well as an accurate (5%) 2A current limit and current clipping protection. The current limit threshold can be dynamically adjusted via an external pin.
2. Key Features:
Small board footprint
33 mΩ MOSFET and RSENSE
Wide operating voltage range: 2.9 V to 26.5 V
Adjustable current limit with 5% accuracy
Current and temperature monitor outputs
Over-temperature protection
Adjustable current limit timer prior to fault
Power-good and fault outputs
Adjustable inrush current control
Undervoltage and overvoltage protection with 2 per cent accuracy
Pin-compatible with the LTC4232 (DFN package only)
Available in 20-pin TSSOP and 16-pin 5mm x 3mm DFN packages
Selected models supplied by Mingjiada Electronics:
LTC4217CDHC
LTC4217CDHC-12
LTC4217CFE
LTC4217HFE
LTC4217IDHC
LTC4217IDHC-12
LTC4217IFE
The LTC4217 series of hot-swap controllers is suitable for applications such as RAID systems, server I/O boards and industrial applications.

[ADI] LTC4224 – Dual-Channel, Low-Voltage Hot Swap™ Controller
1. Overview: The LTC4224 dual-channel, low-voltage Hot Swap™ controller enables the safe insertion and removal of circuit boards from a live backplane. It utilises external N-channel MOSFETs to control two power supplies and can operate normally with one power supply as low as 1V (provided the other power supply is 2.7V or higher). The LTC4224 is capable of ramping up the supply voltages in any order and at an adjustable ramp rate.
2. Key Features:
Enables safe insertion and removal of circuit boards on a live backplane
Controls load voltages from 1 V to 6 V
No gate components required
Adjustable current limit and circuit breaker
Limits peak fault current within ≤1 μs
No external timing capacitors required
Adjustable power supply voltage ramp-up rate
Gate drive for external N-channel MOSFETs
LTC4224-1: Locks out after a fault
LTC4224-2: Automatically retries after a fault
10-pin MSOP and 3mm x 2mm DFN packages
