General Description

The TPIC2802 octal intelligent-power switch is a monolithic BIDFET† integrated circuit designed to sink currents up to 1 A at 45 V simultaneously at each of eight driver outputs under serial input data control.

Furthermore, use of a Darlington output structure enables an 80% reduction in the on-state supply current compared with earlier designs.

Status of the individual driver outputs is available in serial data format.

Overview

• 8-Bit Serial-In Parallel-Out Driver • 1-A Output Current Capability Per Channel or 8-A Total Current • Overcurrent Limiting and Out-of-Saturation Voltage Protection on Driver Outputs • Contains Eight Open-Collector Saturating Sink Outputs With Low On-State Voltage • High-Impedance Inputs With Hysteresis Are Compatible With TTL or CMOS Levels • Exceptionally Low On-State Supply Current 50 mA • Very Low Standby Power 20 mW Typical • Status of Output Drivers May Be Monitored at Serial Output • 3-State Serial Output Permits Serial Cascading or Wire-AND Device Connections • 45-V Transient Clamping With Inductive Switching on Outputs, 20-mJ Rating Per Driver Output TPIC2802 OCTAL INTELLIGENT-POWER SWITCH WITH SERIAL INPUT SLIS013 – APRIL 1992 KV PACKAGE (TOP VIEW) 15 Y4 14 Y5 13 Y6 12 Y7 11 RST 10 VCC 9 SO 8 GND 7 SI 6 SCLK 5 SIOE 4 Y0 3 Y1 2 Y2 1 Y3 The tab is electrically connected to GND.
