Description

The HIP9020 is a Vehicle Speed Sensor (V

receives sinusoidal vehicle speed information from a

speedometer signal source. The signal is ampliﬁed and

squared before frequency processing is done. The circuit

provides pin programmable integer prescaler and postscaler

dividers to scale the output frequencies. The prescaler

divider output of the frequency doubler is mode selected for

1 and 6 through 11. The postscaler mode is selected to the

Output 3 with a divide by 1 or 2. The four V

open collector drivers.

Speed Sensor Input (SSI) - When current limited with a

40k

SSI input is capable of functioning over a wide range of input

signal. The limiter and squaring action is derived from the

zero crossing of the input signal. The signal is converted into

a square wave with a controlled hysteresis squaring

ampliﬁer.

Power Supply - The power supply pin 2 input is intended to

operate from a 5.0V

sources are derived from a temperature stable bandgap;

including an optional 5.7V shunt regulator which may be

used as shown in Figure 2.

Output Drivers - Each output driver is an open NPN collector

with a zener clamp level of typically 35V and short circuit

current limiting. Each output is capable of sinking 15mA of

current.
