nanoPower Supply Supervisors with Glitch-

Free Power-Up

MAX16161/MAX16162

General Description

Benefits and Features

The MAX16161/MAX16162 are ultra-low current, single-

channel supervisory ICs. The devices monitor the power

supply voltage and assert a reset when the input voltage

falls below the reset threshold. After the monitoring volt-

Voltage Processor Cores)

age rises above the factory-set threshold voltage (V ),

the reset output remains asserted for the reset timeout

period and then deasserts, allowing the target microcon-

troller or microprocessor to leave the reset state and begin

operating.

● MR Debounce Circuitry (MAX16161)

● Separate V

and V Inputs (MAX16162)

● Multiple Available Reset Timeout Periods

● Threshold Voltage Options

• 1.7V to 4.85V (MAX16161)

• 0.6V to 4.85V (MAX16162)

Unlike conventional supervisors, which are unable to con-

trol the reset output state when V

is very low, the

MAX16161/MAX16162 reset output is guaranteed to re-

main asserted until after a valid V is achieved. This

is especially important to avoid low-voltage cores leaving

the reset state during power-up or power-down. This also

improves performance when using the MAX16161/

MAX16162 as simple power supply sequencers, because

the devices do not cause a transient enable of a down-

stream power supply due to output glitches.

● -40°C to +125°C Operating Temperature Range

Typical Application Circuit

1.7V TO 5.5V

The MAX16161 features a manual reset (MR) input that

asserts a reset when it receives an appropriate input sig-

nal, which can be either active-low or active-high, depend-

ing on the option. The MAX16162 has no MR input. In-

stead, it has separate V

and V pins, allowing thresh-

RST

old voltages as low as 0.6V. The reset output is active-low

open-drain, and the MAX16161/MAX16162 offer multiple

available reset timeout period options.

The MAX16161/MAX16162 are specified over the -40°C

to +125°C temperature range and are available in tiny,

ages. The MAX16162 is also available in a 5-pin SOT23

package.
