Quad Inverting Power Drivers with Serial

Diagnostic Interface

HIP0080, HIP0081The 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.

HIP0080, HIP0081The 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.

HIP0080, HIP0081Filters 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.

HIP0080, HIP0081For normal operating conditions, a

3.5V. The internal bandgap and bias supply function

includes a 5V regulated supply for the low voltage signal

and logic circuits.
