Description

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 HIP0080, HIP0081The HIP0080/0081  4 input drivers and their respective diagnostic filters are controlled by one ENABLE input.

The inputs of HIP0080, HIP0081The HIP0080/0081 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 pulldown resistors of approximately 100kW. This switches off any channel that has an unterminated input.
 
HIP0080, HIP0081The HIP0080/0081 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.

HIP0080, HIP0081The HIP0080/0081 For 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.
