DESCRIPTIONThe TDE1897R/TDE1898R is a monolithic Intelli-
gent Power Switch in Multipower BCD Technol-
ogy, for driving inductive or resistive loads. An in-
ternal Clamping Diode enables the fast demag-
netization of inductive loads.
Diagnostic for CPU feedback and extensive use
of electrical protections make this device inher-
ently indistructible and suitable for general pur-
pose industrial applications.

DIAGNOSTIC TRUTH TABLE(*) According to the intervention of the current limiting block.
(**) A cold lamp filament, or a capacitive load may activate the current limiting circuit of the IPS, when the IPS is initially turned on. TDE1897
uses Diag2 to signal such condition, TDE1898 does not.

APPLICATION INFORMATIONDEMAGNETIZATION OF INDUCTIVE LOADS
An internal zener diode, limiting the voltage
across the Power MOS to between 45 and 55V
(Vcl), provides safe and fast demagnetization of
inductive loads without external clamping devices.
The maximum energy that can be absorbed from
an inductive load is specified as 200mJ (at
Tj = 85°C).
To define the maximum switching frequency three
points have to be considered:
1) The total power dissipation is the sum of the
On State Power and of the Demagnetization
Energy multiplied by the frequency.
2) The total energy W dissipated in the device
during a demagnetization cycle (figg. 2, 3) is:
W = Vcl L [Io – Vcl – Vs log
1 + Vs
Vcl – Vs
Where:
Vcl = clamp voltage;
L = inductive load;
RL = resistive load;
Vs = supply voltage;
IO = ILOAD
3) In normal conditions the operating Junction
temperature should remain below 125°C.
