DESCRIPTION
The DRV591 is a high-efficiency, high-current power
amplifier ideal for driving a wide variety of
thermoelectric cooler elements in systems powered
from 2.8 V to 5.5 V. PWM operation and low output
stage on-resistance significantly decrease power
dissipation in the amplifier.
The DRV591 is internally protected against thermal and
current overloads. Logic-level fault indicators signal
when
the
junction
temperature
approximately 130
°
C to allow for system-level
shutdown before the amplifier’s internal thermal
shutdown circuitry activates. The fault indicators also
signal when an over-current event has occurred. If the
over-current circuitry is tripped, the DRV591
automatically resets (see application information
section for more details).
has
reached
The PWM switching frequency may be set to 500 kHz
or 100 kHz depending on system requirements. To
eliminate external components, the gain is fixed at
approximately 2.3 V/V.
