The NA and NB have the ability of sink current. INA=INB=X and EN=L, OUTA and OUTB are low level in off state, here the power NMOS NA and NB are off, the enable NMOS ENA and ENB are on. The ENA and ENB only pull down the OUTA and OUTB, and they haven’t the ability of sink current.

V1.7 6 January 2018 PROTECTION FUNCTION THERMAL SHUTDOWN (TSD) CIRCUIT The PT5126 includes a thermal shutdown circuit, which turns the output transistors off when the junction temperature (Tj) exceeds 175°C (typ.). The output transistors are automatically turned on when Tj cools past the shutdown threshold, which is lowered by a hysteresis of 30°C. TSD = 175°C ΔTSD = 30°C * In thermal shutdown mode, the circuits powered by VCC are work normal, and the circuits powered by VM are shut down. UNDER VOLTAGE LOCKOUT (UVLO) CIRCUIT The PT5126 includes an under voltage lockout circuit, which puts the output transistors in the high-impedance state when VCC decreases to 2.13V (typ.) or lower. The output transistors are automatically turned on when VCC increases past the lockout threshold, which is raised to 2.21 V by a hysteresis of 0.08 V. * In UVLO shutdown mode, a part of circuits powered by VCC are work normal, and the circuits powered by VM are shut down. SHOOT-THROUGH CURRENT PROTECTION During Dead Time (Shoot through current circuit is operated.), Power MOS both of HI side and Low side are turned off. But in this time, internal parasitic diode is turned on according to current direction.
