We have already tried to set maximum OCP threshold and deglitch time (11 both) on board SN1152, but it is not better: 11--OCP OCP threshold 11--OCPDEG OCP deglitch time 01 --TDRIVEN Low-side gate drive time 01 --TDRIVEP High-side gate drive ti...
theDRV8705-Q1 detects a VDSovercurrent condition. The voltage threshold and deglitch time can be adjusted through the VDS_LVL and VDS_DG register settings. Additionally, in independent half-bridge and split HS/LS PWM control (BRG_MODE = 00...
When the input voltage returns below VOVP – Vhys(OVP) (but is still above UVLO), the FET Q1 is turned on again after a deglitch time of tON(OVP) to ensure that the input supply has stabilized. Input Overcurrent Protection The overcurrent threshold is programmed by a resistor R(ILIM) ...
The over-current protection is programmed by a resistor connected from ILIM pin to the ground. When any of the monitored parameters are over the threshold, the IC removes the power from the charging system by turning off an internal switch. All protections also have deglitch time against false...
built-in charge pump is used to drive the N-channel MOSFET that is free of parasitic body diode to eliminate any reversed current flow across the switch when it is powered off. OC is open-drain output report over-current or over-temperature event and has typical 9ms deglitch timeout ...
Charge Current OCP Timing Diagram Battery Over-Voltage Protection The battery over-voltage threshold, BVOVP, is internally set to 4.35V. If the battery voltage exceeds the BVOVP threshold, the FET Q1 and Q2 are turned off after a deglitch time of tDGL(BOVP). The FET is turned on once ...
The CXPR7164 provides complete Li+ charger protection against input over-voltage, input over-current and overtemperature. When any of the monitored parameters is over the threshold, the IC turns off the charging current. All protections also have deglitch time against false triggering due to voltag...
The CXPR7163 provides complete Li+ charger protection against Input over-voltage, input over-current and overtemperature. When any of the monitored parameters is over the threshold, the IC turns off the charging current. All protections also have deglitch time against false triggering due to voltag...
choose TOFF to be either 40 μs or 60 μs. "Or, from the point of view of FET's SOA, is this overcurrent deglitch time configured?" Overcurrent deglitch is not configured. Up0TrueDown
When the input voltage returns below VOVP – Vhys(OVP) (but is still above UVLO), the FET Q1 is turned on again after a deglitch time of tON(OVP) to ensure that the input supply has stabilized. Figure 17 shows the recovery from input OVP. 7.3.2 Input Overcurrent Protection The over...
