1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The L9805 is a Super Smart Power device suited
to drive resistive and inductive loads under soft-
ware control. It includes a ST7 microcontroller and
some pheripherals. The microcontroller can exe-
cute the software contained in the program
EPROM/ROM and drive, through dedicated regis-
ters, the power bridge.
The internal voltage regulators rated to the auto-
motive environment, PWM modules, CAN trans-
ceiver and controller, ISO 9141 transceiver, tim-
ers, temperature sensor and the AtoD converter
allow the device to realize by itself a complete ap-
plication, in line with the most common mechatron-
ic requirements.
1.2 OTP, ROM AND EPROM DEVICES
For development purposes the device is available
in plastic HiQuad package without window rating
in the OTP class.
Mass production is supported by means of ROM
devices.
Engineering samples could be assembled using
window packages. These are generally referenced
as “EPROM devices”.
EPROM devices are erased by exposure to high
intensity UV light admitted through the transparent
window. This exposure discharges the floating
gate to its initial state through induced photo cur-
rent.
It is recommended to keep the L9805 device out of
direct sunlight, since the UV content of sunlight
can be sufficient to cause functional failure. Ex-
tended exposure to room level fluorescent lighting
may also cause erasure.
An opaque coating (paint, tape, label, etc...)
should be placed over the package window if the
product is to be operated under these lighting con-
ditions. Covering the window also reduces IDD in
power-saving modes due to photo-diode leakage
currents.
An Ultraviolet source of wave length 2537 Å yield-
ing a total integrated dosage of 15 Watt-sec/cm2 is
required to erase the EPROM. The device will be
erased in 40 to 45minutes if such a UV lamp with a
12mW/cm2 power rating is placed 1 inch from the
device window without any interposed filters.
OTP and EPROM devices can be programmed by
a dedicated Eprom Programming Board and soft-
ware that are part of the development tool-set.
