IC
FOR SENSORS WITH DIFFERENT CONDUCTANCE
Functional Description
Designed IC is an integrated circuit (IC) of the
amplifier for sensors with different conductance.
IL1815 – is an IC of adaptive amplifier
increasing analog signal from the sensor and
transmitting a strobe of pulses from IC output
into electrical circuit of motor engine control
device. The amplifier ensures one short output
pulse leading edge of which coincides with
negative half-wave, crossing zero of input
analog signal produced by alternating magnetic
field of inductive sensor coil.
Functions
IC is purposed for application in automotive electronics in injection controller block as
well as in engine control system for:
crankshaft position (condition) control;
Switching when crossing zero;
engine rotation speed control;
tachometer (rotation speed measurement);
engine check (testing).
IC IL1815 is analog to microcircuit of the third integration scale and comprises 131 elements.
The circuit is implemented in 14-pin DIP-package of MS-001AA (IL1815N) type and in 14-pin SO-
package of MS-012AB (IL1815D) type.
Connection of loading of 1 kOhm to IC output (to pin 10) is tolerable.
Features
Adaptive hysteresis
One-polar power supply mode
Influence of ground on input
Precise choice of the initial ignition moment
Operation in the supply voltage range of 2,5 V up to 12 V
control of input (pin 3) by signal coming into external resistor with amplitude from 75 mV up to
120V.
