UNISONIC TECHNOLOGIES CO., LTD UU6046B Preliminary LINEAR INTEGRATED CIRCUIT REAR WINDOW HEATING TIMER DESCRIPTION The bipolar integrated circuit UTC UU6046B 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. DIP-8 SOP-8 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 VBatt ORDERING INFORMATION Ordering Number Lead Free UU6046BG-D08-T - Halogen Free UU6046BG-D08-T UU6046BG-S08-R Package Packing DIP-8 SOP-8 Tube Tape Reel UU6046BL-D08-T (1) Packing Type (1) T: Tube, R: Tape Reel (2) Package Type (3) Green Package (2) D08: DIP-8, S08: SOP-8 (3) L: Lead Free, G: Halogen Free and Lead Free MARKING DIP-8 8 7 6 5 UTC UU6046B 1 2 3 4 SOP-8 Date Code L: Lead Free G: Halogen Free Lot Code www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 6 QW-R106-009.a UU6046B 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 Reference point, 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-R106-009.a UU6046B 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.
