MAXIM Integrated Products, represented in Australia by Arrow Electronics , has introduced the MAX5918/MAX5919 low-voltage, dual hot-swap controllers.

The MAX5918/MAX5919 allow the safe insertion and removal of circuit line cards with multiple supplies from a live backplane.

Rated for systems with 1V to 13.2V supplies, the devices limit the inrush current to the load and provide protection against overcurrent conditions and load transients.

The MAX5918/MAX5919 are ideal for systems that distribute low voltages to hot-swappable line cards. The devices' low 25mV circuit breaker thresholds are well suited for low-voltage supplies.

The MAX5918/MAX5919 include a VariableSpeed/BiLevel circuit-breaker response feature that protects against overcurrent conditions and prevents nuisance trips caused by noise and load transients.

After a fault condition, the devices provide latched or auto-retry fault management.

Both devices allow independent control of two separate supplies and can be configured for power-supply sequencing by programming delays on the ON/OFF inputs.

Other features include undervoltage lockout (UVLO), output undervoltage/overvoltage monitoring or protection, adjustable circuit-breaker threshold and startup period.

The MAX5918/MAX5919 are available in 16-pin QSOP packages and operate over the extended temperature range (-40°C to +85°C).
