PC33993DWB

The PC33993DWB is one member of the 33993 family which is designed as the multiple switch detection interface that has two modes of operation: the sleep mode and normal model. The sleep mode of PC33993DWB provides low quiescent current and enables the wake up features of the device. The normal mode allows program-ming of the device and supplies switch contacts with pull-up or pull down current as PC33993DWB monitors switch change of state. Also PC33993DWB is packaged in the 32-pin Wide Body SOIC, reducing circuit board area.

Features of the PC33993DWB are:(1)designed to operate 5.5 V </= VPWR </= 26 V; (2)switch input voltage range -14 V to VPWR, 40 V max; (3)interfaces directly to microprocessor using 3.3/5.0 V SPI protocol; (4)selectable wake up on change of state; (5)selectable wetting current (16 mA or 2 mA); (6)8-programmable input (switches to battery or ground); (7)14-switch to ground inputs; (8)standby current < 100 A, VDD standby current < 15 A; (9)active interrupt (INT) on change of switch state.

The absolute maximum ratings of the PC33993DWB can be summarized as:(1)VDD supply voltage:-0.3 to 7.0 VDC;(2)CS, SI, SO, SCLK, INT, AMUX:-0.3 to 7.0 VDC;(3)switch input voltage range:-14 to 40 VDC;(4)frequency of SPI operation (VDD=5.0 V):6 MHz;(5)ESD voltage human body model:4000 V;(6)ESD voltage machine model: 200 V;(7)storage temperature: -55 to +150 °C;(8)operating case temperature: -40 to +125 °C;(9)operating junction temperature:-40 to +150 °C;(10)power dissipation:1.7 W;(11)maximum junction temperature:-40 to + 150 °C;(12)thermal resistance, junction-to-ambient plastic package:74 °C/W.
