MAX14527

The MAX14527/MAX14528 are also protected against overcurrent events with an internal thermal shutdown. The MAX14527/MAX14528 are offered in a small, 8-pin TDFN-EP package and operate over the -40°C to +85°C extended temperature range. The MAX14527/MAX14528 overvoltage protection devices feature a low 100m (typ)RON internal FET and protect low-voltage systems against voltage faults up to +28V. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected components. The overvoltage protection threshold can be adjusted with optional external resistors to any voltage between 4V and 8V. With the OVLO input set below the external OVLO select voltage, the MAX14527/MAX14528 automatically choose the internal ±2.5% accurate trip thresholds. The internal overvoltage thresholds (OVLO)are preset to 5.75V typical (MAX14527)or 6.76V typical (MAX14528).

The features of MAX14527 can be summarized as (1)input voltage protection up to +28V; (2)preset internal ±2.5% accurate OVLO thresholds 5.75V (MAX14527)/ 6.76V (MAX14528); (3)adjustable overvoltage protection trip level; (4)integrated 100m: (typ)n-Channel MOSFETSwitch; (5)soft-start to minimize in-rush current; (6)automatic overvoltage protection trip-level selection; (7)internal 15ms startup delay; (8)thermal shutdown protection; (9)8-Pin TDFN (2mm x 2mm)Package; (10)-40°C to +85°C junction temperature.

The absolute maximum ratings of MAX14527 are (1)IN: -0.3V to +30V; (2)OUT: -0.3V to (VIN + 0.3V); (3)OVLO:-0.3V to +6V; (4)continuous IN current: 1A; (5)peak IN current (Note 1):5A; (6)continuous OVL°Current: 50A; (7)lead temperature (TA = +70°C)8-Pin TDFN (derate 11.9mW/°C above +70°C): 954mW; (8)package junction-to-ambient thermal resistance (JA)(Note 2): 83.9°C/W; (9)package 10-Pin TDFN, multilayer board (JC)(Note 2): 37°C/W; (10)supply voltage: -40°C to +85°C; (11)storage temperature range:+150°C; (12)junction temperature: -65°C to +150°C; (13)lead temperature (soldering): +300°C.
