TYPICAL APPLICATIONS
INTRODUCTION
calculated by multiplying the current area under the current
curve (I A ) times the clamp voltage (V CL ) (see Figure 13 ).
Characterization of the output clamps, using a single pulse
non-repetitive method at 0.3A, indicates the maximum
energy to be 50mJ at 150 ° C junction temperature per output.

All outputs consist of a power MOSFET with an integral
substrate diode. During reverse battery condition, current will
flow through the load via the substrate diode. Under this
circumstance relays may energize and lamps will turn on. If
load reverse battery protection is desired, a diode must be
placed in series with the load.

Over-temperature detect circuits are specifically
incorporated for each individual output. The shutdown
following an over temperature condition depends on the
control bit set in the Global Shutdown / Retry Control register.
Each independent output shuts down at 155°C to 180°C.

When an output shuts down due to an Over-temperature
Fault, no other outputs are affected. The MCU recognizes the
fault by a logic [1] in the Fault Status bit (bit 23 in the SO
Response register). After the 33996 has cooled below the

switch point temperature and 10°C hysteresis, the output will
function as defined by the shutdown / retry bit 17 in the Global
Shutdown/Retry Control register.
The 33996 device requires external reverse battery
protection on the VPWR pin.
