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 100kΩ. 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
Reset turns off all outputs when the VCC 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.
