Thanks to the self-adaptive dead-time circuitry, the low side MOSFET of each leg is driven in the opposite
phase of the high side one without any conflict. Thus, the single IN1 signal turns on the leg M1 (and IN2, the
output M2). Consequently, when both IN1 and IN2 are low, the quiescent state of the H-bridge is the Braking
Mode (the two low side MOSFETs on). The over-temperature circuitry and the two over-current protections
(one per leg) protect the IC and flag the DG pin. The thermal shutdown also covers the body diode over-
heating. Fault conditions are reset by cycling the corresponding IN1(2) input. Each leg appears independent
so that the PWM soft-start management is greatly simplified and makes the 20kHz oscillator block almost a
separate function. The positive input of the PWM comparator is accessible on the SS pin. An external analog
voltage or a RC network can either drive the duty cycle. It has to be said that a clock signal (< 20 kHz) applied
on this input will directly drive the low side MOSFETs. A 5V voltage source is embedded in the I.C ( switched
off while in the sleep mode ) so that no additional power supply is needed for the soft-start RC time constant.
Its capacitor is discharged through the ‘’ SS reset ‘’ circuitry every time IN1 equals IN2. Thus, the soft-start
sequence is ready to operate whichever the formerly braking mode was.
