All rights reserved. 22.May.2013 Rev.006 TSZ22111 ・ 14 ・ 001 www.rohm.com Voltage Detector IC Series Low Voltage Free Delay Time Setting CMOS Voltage Detector IC Series BU42xx series BU43xx series ● General Description ROHM’s BU42xx and BU43xx series are CMOS Voltage Detector ICs with adjustable output delay. It is a high-accuracy, low current consumption Voltage Detector IC series with a built-in delay circuit. The lineup was established with two output types (Nch open drain and CMOS output) and detection voltages range from 0.9V to 4.8V in increments of 0.1V, so that the series may be selected according to application. ● Features Delay Time Controlled by external Capacitor Two output types (Nch open drain and CMOS output) Ultra-low current consumption Wide operating temperature range Very small and low height package Package SSOP5 and SOP4 is similar to SOT-23-5 and SC-82 respectively (JEDEC) ● Key Specifications Detection voltage: 0.9V to 4.8V (Typ.) 0.1V steps High accuracy detection voltage: ±1.0% Ultra-low current consumption: 0.55µA (Typ.) Operating temperature range: -40°C to +125°C ● Package SSOP5: 2.90mm x 2.80mm x 1.25mm SOP4: 2.00mm x 2.10mm x 0.95mm VSOF5: 1.60mm x 1.60mm x 0.60mm ● Applications Circuits using microcontrollers or logic circuits that require a reset. ● Typical Application Circuit ● Connection Diagram & Pin Descriptions SSOP5 SOP4 VSOF5 PIN No. Symbol Function PIN No. Symbol Function PIN No. Symbol Function 1 VOUT Reset output 1 GND GND 1 VOUT Reset output 2 VDD Power supply voltage 2 VDD Power supply voltage 2 SUB Substrate* 3 GND GND 3 CT Capacitor connection terminal for output delay time 3 CT Capacitor connection terminal for output delay time 4 N.C.
