Not subject to production test, specified by design. 2. CCPC1 = CCPC2 = 100 nF, CCP = 220 nF. 3. In case of short to battery. This pin is not protected from short to ground. 2.4.5 Gate driver The electrical characteristics related to the gate driver are valid for VCP > VDH + 8.5 V. VDH = 6 V to 28 V; VDD = 3.0 V to 5.5 V, Tj = -40 °C to 150 °C, VCP > VDH + 8.5 V, all voltages with respect to ground, positive current flowing into pin except for IGLx and IGHx (unless otherwise specified). The gate source and sink current level can be affected in case of high SHx/GHx slew rate due to capacitive current injected into the GATE pin from an external MOS miller capacitor. This behavior is described in a dedicated application note. Table 11. Gate driver Symbol Parameter Test condition Min Typ Max Unit Ionx Gate source current, only ISTEP1x and ISTEP2x ISTEP1_CONFx = ISTEP2_CONFx = 0000 -50% -0.72 +50% mA Ioffx Gate sink current, only ISTEP1x and ISTEP2x ISTEP1_CONFx = ISTEP2_OFF_CONFx = 0000 -50% 0.88 +50% mA Ionx Gate source current ISTEP1_CONFx = ISTEP2_CONFx = 0001 ISTEP3_CONFx = 0000 -50% -1.58 +50% mA Ioffx Gate sink current ISTEP1_CONFx = ISTEP2_OFF_CONFx = 0001 ISTEP3_CONFx = 0000 -50% 1.77 +50% mA Ionx Gate source current, only ISTEP1x and ISTEP2x ISTEP1_CONFx = ISTEP2_CONFx = 0010 -50% -2.6 +50% mA Ioffx Gate Sink Current, only ISTEP1x and ISTEP2x ISTEP1_CONFX = ISTEP2_OFF_CONFx = 0010 -50% 2.6 +50% mA Ionx Gate source current ISTEP1_CONFx = ISTEP2_CONFx = 0011 ISTEP3_CONFx = 0001 -45% -3.3 +45% mA Ioffx Gate sink current ISTEP1_CONFx = ISTEP2_OFF_CONFx = 0011 ISTEP3_CONFx = 0001 -45% 3.5 +45% mA L99MH98 Electrical specifications DS14611 - Rev 3 page 10/147 |
