MAX16052/MAX16053  
High-Voltage, Adjustable  
Sequencing/Supervisory Circuits  
General Description  
Benefits and Features  
Less External Circuitry Results in Smaller Solution Size  
The MAX16052/MAX16053 are a family of small, low-power,  
high-voltage monitoring circuits with sequencing capability.  
These miniature devices offer very wide flexibility with an  
adjustable voltage threshold and an external capacitor-  
adjustable time delay. These devices are ideal for use in  
power-supply sequencing, reset sequencing, and power  
switching applications. Multiple devices can be cascaded  
for complex sequencing applications.  
• Open-Drain (28V Tolerant) Output Allows  
Interfacing to 12V Intermediate Bus Voltage  
• Operates from V  
of 2.25V to 28V  
CC  
• Small 6-Pin SOT23 Package  
Ideal for Use in Power-Supply Sequencing, Reset  
Sequencing, and Power-Switching Applications  
• Active-High Logic-Enable Input  
• 1.8% Accurate Adjustable Threshold Over Temperature  
A high-impedance input (IN) with a 0.5V threshold  
allows an external resistive-divider to set the monitored  
threshold. The output (OUT) asserts high when the input  
voltage rises above the 0.5V threshold and the enable  
input (EN) is asserted high. When the voltage at IN falls  
below 0.495V or when the enable input is de-asserted  
(EN = low), the output deasserts (OUT = low). The  
devices provide a capacitor programmable delay time  
from when the voltage at IN rises above 0.5V to when the  
output is asserted.  
Fully Specified from -40°C to +125°C for Reliability in  
Extreme Temperatures  
Low Supply Current (18µA typ) Reduces Power  
Consumption  
Applications  
Medical Equipment  
Intelligent Instruments  
Portable Equipment  
Computers/Servers  
● Critical μP Monitoring  
Set-Top Boxes  
The MAX16052 offers an active-high open-drain out-  
put while the MAX16053 offers an active-high push-  
pull output. Both devices operate from a 2.25V to 28V  
supply voltage and feature an active-high enable input.  
The MAX16052/MAX16053 are available in a tiny 6-pin  
SOT23 package and are fully specified over the automo-  
tive temperature range (-40°C to +125°C).
