Pin Pin Name Pin Function Formal Name Definition 1 PHASEA Digital Output Phase A Totem Pole output of Phase A comparator. This output is low when the voltage on PA_HS_S (Source of High Side FET) is less than 50% of VSUP 2 PGND Ground Power Ground Power ground for charge pump 3 EN1 Digital Input Enable 1 Logic signal input must be high (ANDed with EN2) to enable any gate drive output. 4 EN2 Digital Input Enable 2 Logic signal input must be high (ANDed with EN1) to enable any gate drive output 5 RST Digital Input Reset Reset input 6, 33, 49, 50, 52, 53 N/C – No Connect Do not connect these pins 7 PUMP Power Drive Out Pump Charge pump output 8 VPUMP Power Input Voltage Pump Charge pump supply 9 VSUP Analog Input Supply Voltage Supply voltage to the load. This pin is to be connected to the common Drains of the external High Side FETs 10 PHASEB Digital Output Phase B Totem Pole output of Phase B comparator. This output is low when the voltage on PB_HS_S (Source of High Side FET) is less than 50% of VSUP 11 PHASEC Digital Output Phase C Totem Pole output of Phase C comparator. This output is low when the voltage on PC_HS_S (Source of High Side FET) is less than 50% of VSUP 54 40 .35 34 33 32 31 30 29 28 39 38 37 36 47 46 45 44 43 42 41 51 50 49 48 53 52 1 15 20 21 22 23 24 25 26 27 16 17 18 19 8 9 10 11 12 13 14 4 5 6 7 2 3 PHASEA PGND EN1 EN2 RST N/C PUMP VPUMP VSUP PHASEB PHASEC PA_HS PA_LS VDD PB_HS PB_LS INT CS SI SCLK SO PC_LS PC_HS AMP_OUT AMP_N AMP_P OC_OUT VPWR N/C N/C VLS N/C N/C PA_BOOT PA_HS_G PA_HS_S PA_LS_G PA_LS_S PB_BOOT PB_HS_G PB_HS_S PB_LS_G PB_LS_S PC_BOOT PC_HS_G PC_HS_S PC_LS_G PC_LS_S N/C VLS_CAP GND1 GND0 VSS OC_TH Transparent Top View |
