XC6135 Series
ETR02041-004
Ultra-Low Power (44nA) Voltage Detector with Separated Sense Pin
■GENERAL DESCRIPTION
The XC6135 series is ultra-low power voltage detector with high accuracy detection, manufactured using CMOS process
and laser trimming technologies.
Since the sense pin is separated from the power supply pin, it allows the IC to monitor the other power supply.
The XC6135 can maintain the state of detection even when voltage of the monitored power supply drops to 0V.
Sense Pin is also suited for detecting low voltages starting from 0.5V.
Ultra-small low height package USPQ-4B05 and standard packages SSOT-24 and SOT-25 which are ideally suited for
small design of portable devices and high densely mounting applications.
UVLO circuit is implemented in order to suppress the floating of RESETB pin (undefined operation) when VIN voltage is
lower than the minimum operation voltage.

*The dissipation pad for the USPQ-4B05 package should be solder-plated in reference mount pattern and metal masking so as to enhance
mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to VSS (No. 3) pin.
