Quad Inverting Power Drivers with Serial

Diagnostic Interface

The HIP0080/0081 Quad Power Drivers contain four

individually protected NDMOS power output transistor

switches to drive inductive and resistive loads such as:

relays, solenoids, injectors, AC and DC motors, heaters

and incandescent lamp displays. The 4 Power Drivers are

low-side switches driven by CMOS logic input control

stages. Each Output Power Driver is protected against

over-current, over-temperature and over-voltage. An

internal drain-to-gate zener diode provides the clamping

protection for over-voltage. Diagnostic circuits provide

ground short, supply short, open load and thermal overload

detection for each of the 4 output stages. Each of the 4

input drivers and their respective diagnostic filters are

controlled by one ENABLE input.

The inputs are CMOS logic compatible and individually

control the output drivers with an active high state for turn-

on. All other control inputs are active high with the

exception of the Chip Select (CS) which is active low. The

DATAIN (DI) and DATAOUT (DO) are positive logic and the

Clock (CLK) input for the Serial Interface is active on the

rising edge of the CLK pulse. All Inputs except the HIP0080

ENABLE have a nominal level of hysteresis. IN1, IN2, IN3,

IN4 and ENABLE have pull-down resistors of

approximately 100k

Ω. This switches off any channel that

has an unterminated input.

Filters are used on the outputs of the fault sensing

comparators to avoid the detection of short duration

transient spikes. The on-chip oscillator is used to clock an

internal shift register in each filter. If the fault condition is

longer than a preset number of clock cycles, the fault

condition is recognized and the respective bit is set in the

diagnostic register. No filter is used in the thermal-overload

feedback circuit and the bit is set when thermal shutdown

occurs.

For normal operating conditions, a Reset turns off all

bandgap and bias supply function includes a 5V regulated

supply for the low voltage signal and logic circuits.
