This driver consists of two independently controlled drivers which are able to provide 200 mA series / 50 mA shunt current to a series / shunt, 1 SH1 Shunt1 SPDT PIN diode switch. The back bias voltage is configurable from 20 V to 250 V. High voltage level 2 C1 Control Logic 1 shifters are integrated so that it can be easily 3 I Bias Voltage BIAS controlled by 3 V or 5 V CMOS logic. While consuming low quiescent current, this driver has a 4 SER1 Series1 typical delay of <8 s when driving 220 pF capacitor 2 5, 8 N/C No Connection load. If needed, the switching speed can be improved by consuming more quiescent power. 6, 7, 13, 14, 15 GND Ground 9 SH2 Shunt2 This driver is packaged in a lead free 7 mm PQFN- 16LD package and is available in tape and reel 10 V Control Voltage CC packaging for high volume applications. 11 C2 Control Logic 2 12 SER2 Series2 16 V Drain Voltage DD 17 Paddle Ground Ordering Information 1. The paddle of the QFN package should be tied to ground. 2. N/C pins (except pin 15) can be grounded. The clearance from high voltage pins should be at least 0.8 mm. Pin 15 must be MADR-010574-000100 Bulk Packaging left open.

Refer to Application Circuit: Driving SPDT Switch with MA4P504-1072T Pin Diodes for configuration of diode bias currents. 5. This sinking bias current is necessary for normal driver operation. The easiest way is to connect a 0402 resistor R between Pin V and BIAS CC Pin I . Then I can be calculated by: I = (V -0.6)/(500+R ). BIAS BIAS BIAS CC BIAS 6. Refer to graph Typ.
