________________General Desc ription
The MAX6315 low-power CMOS microprocessor (μP)
supervisory circuit is designed to monitor power sup-
plies in μP and digital systems. It provides excellent cir-
cuit reliability and low cost by eliminating external
components and adjustments. The MAX6315 also pro-
vides a debounced manual reset input.
This device performs a single function: it asserts a reset
signal whenever the V
CC
supply voltage falls below a
preset threshold or whenever manual reset is asserted.
Reset remains asserted for an internally programmed
interval (reset timeout period) after V
CC
has risen above
the reset threshold or manual reset is deasserted. The
MAX6315’s open-drain
RESET
output can be pulled up
to a voltage higher than V
CC
.
The MAX6315 comes with factory-trimmed reset thresh-
old voltages in 100mV increments from 2.5V to 5V.
Preset timeout periods of 1ms, 20ms, 140ms, and
1120ms (minimum) are also available. The device
comes in a SOT143 package.
For microcontrollers (μCs) and μPs with bidirectional
reset pins, see the MAX6314 data sheet.
