TLE7188F
General Product Characteristics
2) For proper start up minimum Vs=6.5V is required
3) Duty cycle is referred to the high side input command (IHx); The duty cycles can be driven continuously and fully operational
4) total current consumption from power net (Vs and VDH)
Note: Within the functional range the IC operates as described in the circuit description. The electrical
characteristics are specified within the conditions given in the related electrical characteristics table.
Note: If the voltage difference between CB2 and SHx is smaller than 2V during normal operation, there is a risk
that the high side output can switch on and off without a corresponding input signal. As soon as this supply
voltage recovers and the input signal changes, the output stage is automatically aligned to the input again.

Note: The load condition “C=22nF; R_Load=1Ω” in the paragraph “Electrical characteristics / Dynamic characteristic” means that
R_Load is connected between the output Gxx and the positive terminal of the C. The negative terminal of the C is connected
to GND and the corresponding Sxx. The voltage is measured at the positive terminal of the C
