UNISONIC TECHNOLOGIES CO., LTD UU6047B Preliminary LINEAR INTEGRATED CIRCUIT REAR WINDOW HEATING TIMER DESCRIPTION The bipolar integrated circuit UTC UU6047B is designed as a window heating timer. Due to time controlled functions, they reduce the current consumptions of high loads i.e., heating resistors. An ON-relay can be switched off after a preset delay time. The relay time can be interrupted manually, whereas a retrigger function is not provided. FEATURES * Delay time range: 3.7s to 20h * Relay driver with Z-diode * RC oscillator determines switching characteristics * Debounced input for toggle switch * Two debounced inputs: ON and OFF * Load-dump protection * RF interference protected * Inputs switched to ground ORDERING INFORMATION Ordering Number Lead Free Halogen Free UU6047BL-D08-T UU6047BG-D08-T UU6047BG-S08-R Package Packing DIP-8 SOP-8 Tube Tape Reel MARKING DIP-8 www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd SOP-8 1 of 6 QW-R106-011.a UU6047B Preliminary PIN CONFIGURATION PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 PIN NAME GND RELAY ON OFF TOGGLE OSC VSTAB VS LINEAR INTEGRATED CIRCUIT DESCRIPTION Ground Relay control output Switch-on input Switch-off input Toggle input RC oscillator input Stabilized voltage Supply voltage BLOCK DIAGRAM OSC 6 Vstab 7 VS 8 Stabilization Power-on reset Load-dump detection Oscillator 1 GND Frequency divider TOGGLE 5 OFF 4 Debouncing Monoflop Relay control output 2 RELAY ON 3 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R106-011.a UU6047B Preliminary LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT Operating Voltage, Static, 5 min VBatt 24 V Ambient Temperature Range TA -40 ~ +125 °C Junction Temperature TJ 150 °C Storage Temperature Range TSTG -55 ~ +125 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
