Test mode
The test mode can be entered by rising the CSN input to a voltage higher than 7.0 V. In the
test mode the inputs CLK, DI, PWM1/2 and the internal 2 MHz CLK can be multiplexed to
data output DO for testing purpose. Furthermore the over-current thresholds are reduced by
a factor of 4 to allow EWS testing at lower current. For EWS testing a special test pad is
available to measure the internal bandgap voltage, the TW and TSD thresholds.
The internal logic prevents that the Hi-Side and Lo-Side driver of the same half-bridge can
be switched on at the same time. In the test mode this combination is used to multiplex the
desired signals according to following table:
Table 18.
