Freescale Semiconductor, Inc.
Pin 1 : Vcc
5V typical power supply pin. Typical supply current is less
than 1.5mA.
Pin 2 : REF-IN-L
Input reference for C2 comparator. This input can be con-
nected directly to REF-OUT, with or without a resistor net-
work, or to an external reference.
Pin 3 : REF-IN-K
Input reference for C1 comparator. This input can be con-
nected directly to REF-OUT, with or without a resistor net-
work, or to an external reference.
Pin 4 : LO
Output of C2 comparator, normally connected to a micro-
controller I/O. If L input > (Ref-in-l + Hyst/2) then output LO is
in high state. If L< (Ref-in-l - Hyst/2) then output LO is in low
state, output transistor ON.
This pin is an open collector structure. A Pull up resistor
should be added to Vcc.
Drive capability of this output is 5mA.
Pin 5 : RXD
Receive output, normally connected to a microcontroller I/
O.
If DIA input > (Ref-in-l + Hyst/2) then output LO is in high
state.
If DIA < (Ref-in-l - Hyst/2) then output LO is in low state,
output transistor ON. This pin has an internal pull up resistor
to Vcc (2K
typ). Drive capability of this output is 5mA
Pin 6 : TXD
Transmission input, normally connected to a microcontrol-
ler I/O.This pin control DIA output. If Txd is high the output
DIA transistor is OFF. If Txd is low the DIA output transistor
is ON.
Pin 9 : DIA
Input / Output Diagnosis Bus line pin. This pin is an open
collector structure, protected against over current and short
circuit to Vbat (Vs). When turning ON (Txd low), this pin will
pull the Bus line to Gnd, the current into DIA will be internally
limited to 60mA typ.
The internal power transistor has a thermal shutdown cir-
cuit, which forces the DIA output OFF in case of over tem-
perature.
DIA is also the C1 comparator input. It is protected against
both positive and negative over voltage by a 38V zener
diode. This pin exhibits a constant input current of 7,5
μ
A.
Pin 10 : GND
Gnd reference for the entire device.
Pin 11 : I1
Bus source current pin. It is normally tied to DIA pin and to
the Bus line.
At static HIGH or LOW level Txd, the current source I1
delivers a current of 3mA (typ). Only during LOW to HIGH
transition, does this current increase to a higher value in
order to charge the key line capacitor (Cl<4nF) in a short
time (see fig 3 and 4).
Pin 12 : L
Input for C2 comparator. This pin is protected against both
positive and negative over voltage by a 38V zener diode.
This L line is a second independent input. It can be used
for wake up sequence in ISO diagnosis or as an additional
input bus line.
This pin exhibits a constant input current of 7.5
μ
A.
Pin 13 : VS
12V typical, or Vbat supply pin for the device. This pin is
protected against over voltage transients.
Pin 14 : REF-OUT
Internal reference voltage generator output pin. Its value
depends on Vs (Vbat) values. This output can be directly
connected to REF-IN L and REF-IN-K, or through a resistor
network. Maximum current capability is 50
μ
A.
