MAX15009, MAX15011 Automotive 300mA LDO Regulators With Switched Output And Overvoltage Protector

The MAX15009 includes a 300mA LDO Regulator a switched output, and an overvoltage protection (OVP) controller to protect downstream circuits from High-Voltage load dump. The MAX15011 includes only the 300mA LDO Regulator and switched output. Both devices operate over a wide supply voltage range from 5V to 40V and are able to withstand load-dump transients up to 45V. The MAX15009 MAX15011 feature short-circuit and thermalshutdown protection. These devices offer highly integrated Power Management solutions for automotive applications such as instrument clusters, climate control, and a variety of automotive power-supply circuits.
The 300mA LDO Regulator consumes 67A quiescent current at light loads and is well suited to power always-on circuits during "key off" conditions. The LDO features independent enable and hold inputs, as well as a Microprocessor (P) reset output with adjustable reset timeout period.
The switched output of the MAX15009 MAX15011 incorporates a low RDS(ON) (0.28, typ) pass Transistor Switch internally connected to the output of the LDO Regulator This Switch features accurate current-limit sensing circuitry and is capable of controlling remote loads. The MAX15009 MAX15011 feature an adjustable current limit and a programmable delay Timer to set the overcurrent det 63d ection blanking time of the Switch and autoretry timeout.
The MAX15009 OVP controller operates with an external enhancement mode N-Channel MOSFET While the monitored voltage remains below the adjustable threshold, the MOSFET stays on. When the monitored voltage exceeds the OVP threshold, the OVP controller quickly turns off the external MOSFET The OVP controller is configurable as a load-disconnect Switch or a voltage limiter.
The MAX15009 MAX15011 are available in a thermally enhanced, 32-pin (5mm x 5mm), TQFN package and are fully specified over the -40C to +125C automotive operating temperature range.
