Description
Large numbers of relay-based applications require the use of a
microprocessor which implements complex system control. In
these systems, there is the need for microprocessor logic supply
voltage, power-on reset circuitry, and watchdog capabilities. The
Allegro
A2550 combines the functions of voltage regulator,
watchdog, and reset, as well as three low-side DMOS relay
driver outputs. Primarily targeted at automotive applications,
this IC is designed to provide robust performance over extended
voltage and temperature ranges.
Three low-side DMOS drivers can drive inductive loads, such
as relay coils. Each driver integrates rugged voltage clamps
which survive automotive load dump pulses up to 48 V. The
40 V rating on VBB also ensures adequate survival in harsh
automotive environments.
A 5 V linear regulator provides 40 mA of output current, with
a tolerance of 2% over the operating temperature range. To
enhance the usefulness of the IC in automotive applications,
the 5 V regulator output, as well as the three low-side driver
outputs are protected against overcurrent conditions.
