HIP0063

Hex Low Side MOSFET Driver with Serial or

Parallel Interface and Diagnostic Fault Control

Description

The HIP0063 is a logic controlled, six channel Low Side Power Driver. As

shown in the Block Diagram, the outputs are controlled via the serial data

interface or, by user option, each output may be independently controlled

from the respective parallel input. In addition, PWM logic switching control

(HLOS) may be directly applied to channels 0 and 1 in parallel, or channels 4

and 5 in parallel.

Output fault conditions may be detected as an output load short to supply

when the output is ON or as an open load/ground short when the output is

OFF. If an over-current short exists at one output, gate drive goes to a low

duty cycle mode. It will remain in the low duty cycle mode until switched off or

the fault is cleared. Fault bits are sent to a fault register to indicate which

channel is at fault. The fault bits are indicated by a logic one and is internally

latched when CS goes low. A fault bit will return to zero when the fault disap-

pears. Either an 8-bit or 16-bit SPI communication mode may be used. Refer

to the application section for bit control information.

supply is greater than 4V typical. The HIP0063 has an internal drain-to-gate

zener which is used to voltage clamp the output drain-to-source voltage of the

MOSFET.

The HIP0063 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 well suited for MOSFET con-

trol in circuits driving lamps, displays, relays, and solenoids in applications

requiring low operating power.
