HIP0045  
Data Sheet  
April 1999  
File Number 4047.2  
1A/50V Octal Low Side Power Driver With  
Serial Bus Control and Fault Protection  
Features  
• Octal NDMOS Output Drivers in a High Voltage Power  
BiMOS Process  
The HIP0045 is a logic controlled, eight channel Octal Serial  
Power Low Side Driver. The serial peripheral interface (SPI)  
utilized by the HIP0045 is a serial synchronous bus compatible  
with Intersil CDP68HC05, or equivalent, microcomputers. As  
shown in the Block Diagram for the HIP0045, each of the open  
drain MOS Output Drivers have individual protection for over-  
voltage and over-current. Each output channel has separate  
output latch control with fault unlatch and diagnostic or status  
feedback. Under normal ON conditions, each output driver is in  
a low voltage, high current state of saturated turn-on.  
• Over-Stress Protection - Each Output:  
- Over-Current Protection . . . . . . . . . . . . . . . . . . . 1A Min  
- Over-Voltage Clamp Protection . . . . . . . . . . . . 50V Typ  
- Thermal Shutdown Protection (2 Channels)  
• Open-Load Detection  
• Power BiMOS Output Configuration  
- Current Latch-Off Protection for 6 Channels; 2 with  
External Drive Input and ORed with SPI Bus Control  
Comparators in the diagnostic circuitry monitor the output  
drivers to determine if an out of saturation condition exists. If a  
fault is sensed, the respective output driver for Channels 0 - 5  
have overcurrent latch-off. Channels 6 and 7 are configured for  
lamp drivers and have current limiting with over-temperature  
latch-off. Channels 0 and 1 have direct parallel drive control for  
PWM applications and are ORed with the SPI Bus control. All  
channels are SPI Bus controlled and sense the output states  
for diagnostic feedback.  
- 2 Channels Configured for Lamp Drivers with Current  
Limiting and Over-Temperature Latch-Off  
• High Speed CMOS Logic Control  
- SPI Bus Controlled Interface  
- Individual Output Latch  
- Individual Fault Unlatch and Feedback  
- Common Reset Line  
• Low Quiescent Current . . . . . . . . . . . . . . . . . . . 5mA Max  
The HIP0045 is fabricated in a Power BiMOS IC process,  
and is intended for use in automotive and other applications  
having a wide range of temperature and electrical stress  
conditions. It is particularly suited for driving relays,  
solenoids and lamps in applications where low standby  
power, high operating voltage, and high output current in  
high ambient temperature conditions is required.

Applications  
• Automotive and Industrial Systems  
• Solenoids, Relays and Lamp Drivers  
• Logic and µP Controlled Drivers  
• Robotic Controls  
The HIP0045 is in a 20 lead plastic Power SOP (PSOP)  
Package with an integral copper ‘slug’ to conduct heat directly  
to a PCB interface or heat sink on the bottom of the package.
