A hysteresis on thresholds and filtering time is implemented. If POWERIN_P ≤ VIN_off_th occurs for an interval longer than T_vin_mon_detect_dly, the fault is asserted and the VIN_UV flag is set. Fault pins are asserted LOW according to FHC configuration and FOR table. If POWERIN_P ≥ VIN_on_th occurs for an interval longer than T_vin_mon_detect_dly, the VIN_UV fault is released. VIN_UV clearing depends on FHC configuration. The reference thresholds for the VIN monitor unit VIN_off_th and VIN_on_th can be separately configured through a dedicated PMBus™ register as follows: VINOFFTH=VINMONtℎlsb×VINOFFTH7:0 (4) VINONTH=VINMONtℎlsb×VINONTH7:0 (5) Where: VIN_MON_th_lsb is the minimum voltage step [89.2 mV]. VIN_OFF_TH/VIN_ON_TH [7:0] are the dedicated PMBus™ configuration bits [0 V ~ 22.8 V]. The default value is VIN_ON_TH =0x07B (11 V) and VIN_OFF_TH = 0x078 (10.7 V). In case VIN_OFF_TH = 0x000 the input voltage monitor function is disabled, and no UV detection is performed. The absolute value of the maximum input voltage slew rate detectable by VIN monitor is given by VIN_adc_lsb/ VIN_adc_latency. STPM098C Functional description DS14440 - Rev 1 page 48/110 |
