Maxim Integrated Products introduces the MAX15009/MAX15011 highly integrated, 300mA automotive linear regulators with a switched output and load-dump protection. Designed to withstand harsh operating conditions, these low-dropout (LDO) regulators operate over a wide, 5V to 40V supply-voltage range, protect against load-dump transients up to 45V, and provide short-circuit and thermal-shutdown protection. To save space and cost in automotive applications, the MAX15009/MAX15011 provide an additional low-resistance switched output that can be used to independently power remote loads. The switched output features a current-limit sensing circuit with an adjustable current limit, as well as adjustable current-limit fault blanking and autoretry delay. The MAX15009/MAX15011 are ideal for instrument clusters, infotainment systems, telematics, and climate control in automotive applications.
The MAX15009/MAX15011 provide independent enable inputs for the linear regulator, switched output, and overvoltage protector (MAX15009 only) for better control of each function. Offering low power consumption, these linear regulators consume only 70 microamps of quiescent current in a stand-alone configuration, and 16 microamps in shutdown mode. Well suited for always-on circuits, these devices provide enable and hold inputs for “key off” conditions. Additionally, to further save cost and improve performance, the MAX15009 integrates an overvoltage-protection (OVP) controller that can be configured as a switch controller or as a voltage limiter. This OVP controller protects downstream circuits from high-voltage load dump, thus enabling the use of lower cost DC-DCs.
The MAX15009/MAX15011 are offered in a thermally enhanced, 5mm x 5mm, 32-pin TQFN package, and are fully specified over the -40 degrees Celsius to +125 degrees Celsius automotive temperature range. Prices start at $1.32 (1000-up, FOB USA).
