Functional Description
The
TLE 4484 G
is a monolithic integrated voltage regulator providing two output
voltages, output Q5 is a 5 V output for loads up to 25 mA and output Q15 is a 15 V output
providing up to 30 mA. The device is based on the Infineon double isolated bipolar
technology
DOPL
with high accuracy polysilicon resistors and is available in the
P-SOT223-4-2
package.
The
TLE 4484 G
is designed to supply systems with a microcontroller (5 V) and a
standard MOS-driver-IC (15 V) under severe conditions and is therefore equipped with
additional protection functions.
Both outputs are protected against overload, short circuit to ground and to the input
voltage. A build-in shutdown-circuit protects the device against overheat.
The IC operates in a wide input voltage range up to 45 V. The output voltages are
regulated to
V
Q5
= 5 V and
V
Q15
= 15 V with a drop voltage less than 1.5 V. The standard
P-SOT223-4-2
package is especially suitable for this kind of application, saves PCB-
board-space and reduces system cost.

ESD-Protection (Human Body Model)
1) The overtemperature protection will be set to 150
°C
min. The voltage regulator should not be operated
continuously at 170
°C
as device reliability will be reduced to 500 h.
Attention: Stresses above those listed here may cause permanent damage to the
device. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
