General Description
The MAX15008 features a 300mA LDO regulator, a volt-
age tracker, and an overvoltage protection (OVP) con-
troller to protect downstream circuits from high-voltage
load dump. The MAX15010 includes only the 300mA
LDO voltage regulator and voltage tracker. Both devices
operate over a wide 5V to 40V supply voltage range and
are able to withstand load-dump transients up to 45V. The
MAX15008/MAX15010 feature short-circuit and thermal-
shutdown protection. These devices offer highly integrat-
ed 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 less than 70µA qui-
escent 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 (µP) reset output with an adjustable reset
timeout period.
The voltage tracker accurately (±3mV) tracks a voltage
applied to its input from either the LDO output or an exter-
nal source. It can supply up to 50mA of current to a
remote sensor, allowing for precise ratiometric tracking in
automotive applications. A separate enable input turns
the tracker on or off, reducing supply current when the
tracker is unused. The voltage tracker also features pro-
tection against battery reversal, an output short circuit to
the battery, or an output-voltage excursion below ground
potential to as much as -5V.
The MAX15008 OVP controller operates with an external
enhancement mode n-channel MOSFET. While the moni-
tored 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 MAX15008/MAX15010 are available in a thermally
enhanced, 32-pin (5mm x 5mm) TQFN package and are
fully specified over the -40°C to +125°C automotive oper-
ating temperature range.
