Rear Window Heating Timer
U6046B / U6047B
Description
The window heating timers are bipolar integrated
circuits. Due to time controlled functions, they reduce the
current consumptions of high loads i.e., heating resistors.
An ON-relay can be switched off after a preset delay time.
The relay time can be interrupted manually, whereas a
retrigger function is not provided.
Features
D Delay time range: 3.7 s to 20 h
D RC oscillator determines switching characteristics
D Relay driver with Z-diode
D Debounced input for toggle switch
D Two debounced inputs: ON and OFF
D Load-dump protection
D RF interference protected
D Protection according to ISO/TR7637-1 (VDE 0839)
D U6046B: Inputs switched to VBatt
D U6047B: Inputs switched to ground

U6046B / U6047B
WFigure 11 shows the input circuit of U6047B. It has an
integrated pull-up resistance (100 k ), RF capacitor
(15 PF) and Z-diode (7 V). The circuit reacts to voltages
less than 2 V. The external protective resistance has a
Wvalue of 2 k and the push-button switch is connected to
GND. Contact current, I, is calculated as follows:

WIt can be increased by connecting a 5.6 k resistor from
the push-button-switch to VBatt as shown in figure 19.
The connecting diodes prevent the current flow to the
input of the Z-diodes when the rocker actuated-switch is
in open-state (current-consumption only in
standby-mode). If necessary, these diodes can be omitted.

Ozone Depleting Substances Policy Statement
It is the policy of TEMIC TELEFUNKEN microelectronic GmbH to
1. Meet all present and future national and international statutory requirements.
2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems
with respect to their impact on the health and safety of our employees and the public, as well as their impact on
the environment.
It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as
ozone depleting substances ( ODSs).
The Montreal Protocol ( 1987) and its London Amendments ( 1990) intend to severely restrict the use of ODSs and
forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban
on these substances.
TEMIC TELEFUNKEN microelectronic GmbH semiconductor division has been able to use its policy of
continuous improvements to eliminate the use of ODSs listed in the following documents.
1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively
2 . Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental
Protection Agency ( EPA) in the USA
3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C ( transitional substances ) respectively.
TEMIC can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain
such substances.
We reserve the right to make changes to improve technical design and may do so without further notice.
Parameters can vary in different applications. All operating parameters must be validated for each customer
application by the customer. Should the buyer use TEMIC products for any unintended or unauthorized
application, the buyer shall indemnify TEMIC against all claims, costs, damages, and expenses, arising out of,
directly or indirectly, any claim of personal damage, injury or death associated with such unintended or
unauthorized use.
