Micrel MIC4832 March 2009 2 M9999-033109-C Ordering Information Part Number Junction Temp. Range Package Lead Finish MIC4832YML –40° to +85°C 8-Pin 3mm × 3mm MLF ® RoHS Compliant / Pb-Free / Halogen Free* MIC4832YMM –40° to +85°C 8-Pin MSOP RoHS Compliant / Pb-Free Note *MLF ® is a GREEN RoHS-compliant package. Lead finish is NiPdAu. Mold compound is Halogen Free. Pin Configuration 8-Pin MSOP (MM) 8-Pin 3mm × 3mm MLF® (ML) Pin Description Pin Number Pin Name Pin Function 1 VDD Supply (Input): 1.8V to 5.5V for internal circuitry. 2 RSW Switch Resistor (External Component): Set switch frequency of the internal power MOSFET by connecting an external resistor to VDD. Connecting the external resistor to GND disables the switch oscillator and shuts down the device. 3 REL EL Resistor (External Component): Set EL frequency of the internal H-bridge driver by connecting an external resistor to VDD. Connecting the external resistor to GND disables the EL oscillator. 4 GND Ground 5 SW Switch Node (Input): Internal high-voltage power MOSFET drain. 6 CS Regulated Boost Output (External Component): Connect to the output capacitor of the boost regulator and connect to the cathode of the diode. 7 VB EL Output: Connect to one end of the EL lamp. Polarity is not important. 8 VA EL Output: Connect to one end of the EL lamp. Polarity is not important. |
