MAX16543GPC+

MAX16543 is an integrated protection IC on a high-power 12V bus with an integrated MOSFET and lossless current sensing. The MAX16543 increases the current capability of the MAX16545B/MAX16545C. The chipset provides monotonic startup with programmable ramp and delay to limit inrush current during startup. System and application includes servers, networking, storage, communication equipment and AC/DC power supplies, integrated protection IC on 12V: circuit breaker/E-fuse, hot swap.

• High density industry’s smallest circuit breaker solution provides more than 75% board area
• Lossless, precise total system current sensing and reporting
• VIN to VOUT short protection during startup
• Very fast fault detection and isolation
• Overtemperature protection, programmable moderate OCP
• Programmable severe OCP provides isolation <lt/> 5μs
• Fail-safe safe OCP provides isolation <lt/> 250ns
• Supply voltage range from 10.8V to 13.2V (12V supply, VIN = 12V ±10%, TA = +32°C)
• 100ns typical output delay (from fault to start of FAULT (active high) falling)
• 12 pin FCQFN package, operating junction temperature range from 0°C to +125°C
