-48V Hot-Swap Controllers with External

and High Gate Pulldown Current

SENSE

General Description

Features

The MAX5921/MAX5939 hot-swap controllers allow a cir-

cuit card to be safely hot plugged into a live backplane.

The MAX5921/MAX5939 operate from -20V to -80V and

are well suited for -48V power systems. These devices

are pin compatible with both the LT1640 and LT4250 and

provide improved features over these devices.

♦ Allows Safe Board Insertion and Removal

from a Live -48V Backplane

♦ Pin-Compatible with LT1640 and LT4250

♦ Circuit Breaker Immunity to Input Voltage Steps

and Current Spikes

The MAX5921/MAX5939 provide a controlled turn-on to

circuit cards preventing damage to board connectors,

board components, and preventing glitches on the

power-supply rail. The MAX5921/MAX5939 provide

undervoltage, overvoltage, and overcurrent protection.

These devices ensure that the input voltage is stable

and within tolerance before applying power to the load.

♦ 450mA GATE Pulldown Current During Short-

Circuit Condition

♦ Exponential GATE Pulldown Current

♦ Withstands -100V Input Transients with No

External Components

♦ Programmable Inrush and Short-Circuit Current

Both the MAX5921 and MAX5939 protect a system

against overcurrent and short-circuit conditions by turn-

ing off the external MOSFET in the event of a fault con-

dition. The MAX5921/MAX5939 protect against input

voltage steps by limiting the load current to a safe level

without turning off power to the load.

Limits

♦ Operates from -20V to -80V

♦ Programmable Overvoltage Protection

♦ Programmable Undervoltage Lockout

The device features an open-drain power-good status

output, PWRGD or PWRGD for enabling downstream

converters (see Selector Guide). A built-in thermal shut-

down feature is also included to protect the external

MOSFET in case of overheating. The MAX5939 features

a latched fault output. The MAX5921 contains built-in

autoretry circuitry after a fault condition.

with Built-In Glitch Filter

♦ Overcurrent Fault Integrator

♦ Powers Up into a Shorted Load

♦ Power-Good Control Output

♦ Thermal Shutdown Protects External MOSFET

The MAX5921/MAX5939 are available in an 8-pin SO

package and operate in the extended -40°C to +85°C

temperature range.
