Detailed Description
The MAX5023/MAX5024 high-voltage linear regulators
include an integrated μP reset circuit and watchdog
timer/adjustable output voltage. The devices guarantee
150mA load drive and are available with preset output
voltages of +3.3V or +5V. The MAX5023 features a
watchdog timer (WDI) with a 1.6s timeout period. The
MAX5024 offers an adjustable output voltage using an
external resistive-divider network between SET and
OUT. The internal reset circuit monitors the regulator
output voltage and asserts a reset output when the reg-
ulator output falls below the μP supply tolerance. Other
features include reverse-voltage protection to -60V,
enable (EN) and hold (
HOLD
) regulator control inputs,
16μA (max) shutdown current, short-circuit protection,
and thermal shutdown.
Regulator
The regulator accepts an input voltage range from
+6.5V to +65V. The MAX5023/MAX5024 offer fixed out-
put voltages of +3.3V and +5V. The MAX5024 also fea-
tures an adjustable output voltage that is implemented
with an external resistive-divider network connected
between OUT, SET, and GND (Figure 1). The MAX5024
automatically determines the feedback path depending
on the voltage at SET. Featured characteristics include
reverse-voltage protection to -60V and enable and hold
regulator control inputs. The
Typical Operating Circuit
shows a self-holding configuration for the MAX5023.
