Test mode
The Test Mode can be entered by rising the CSN input to a voltage higher than 9.5V. In the
test mode the inputs CLK, DI, PWM1/2, the internal 2MHz CLK, OL and OC can be
multiplexed to output DO and Iref, Tsens1-4 and Vbgp can be multiplexed to input
CM/PWM2.
Furthermore the over-current thresholds are reduced by a factor of 4 to allow EWS testing at
lower current.
The internal logic prevents that the High-Side and Low-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.
