DUAL HOT-SWAP CONTROLLERS WITH INDEPENDENT ON/OFF CONTROL FROM MAXIM ALLOW POWER-SUPPLY SEQUENCING
SUNNYVALE, CA-September 10, 2002-Maxim Integrated Products (NASDAQ: MXIM) introduces 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). Prices start at $3.47 (1000-up, FOB USA).
