说明

The MAX15162/MAX15162A devices are dual-channel circuit-breaker ICs. The devices integrate a dual-channel controller with dual 140mΩ (in WLP, 180mΩ in TQFN) power MOSFETs and electronic circuit-breaker protection in a single package.

These devices feature constant power control during startup to keep the MOSFET operating under Safe Operating Area (SOA). The devices provide robust overcurrent protection with programmable current-limit level, and adjustable overcurrent shutdown delay for better immunity against system noises and load transient. The current monitoring pins provide a current sense accuracy of ±3% for each channel. When there is short-circuit at the output, a fast current limit comparator turns off MOSFETs within 200ns to isolate the load from the input. During a fault condition, the MAX15162A enters auto-retry mode and the MAX15162 enters latch off mode. For both devices, the ALRT pin asserts a fault indication. The MAX15162/MAX15162A can be configured as two independent channels or two parallel channels for one common output.

The devices feature a number of protection features including; IN-to-OUT short-circuit protection, output short-circuit protection, startup watchdog timer, input undervoltage lockout and internal overtemperature protection.

The MAX15162/MAX15162A are available in a 24-pin, 4mm x 4mm TQFN package and 16-bump, 2mm x 2mm WLP package and are rated over the -40°C to +105°C operation temperature range.
