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 100kΩ. 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
outputs when the V_CC level drops below 3.5V. The internal
bandgap and bias supply function includes a 5V regulated
supply for the low voltage signal and logic circuits.
