Logic Inputs
Logic Input Voltage Range:
Absolute Max :
-0.3 V ... 10 V
Wake Up Function:
(G_EN)
4.5 V ... VCC2
During Wake-Up the logic is supplied from the G_EN pin.
Low Drop Linear Regulator
The low drop linear regulator provides the 5.0 V for the logic section of the driver, the Vgs_ls buffered at LR_OUT and the +13.5 V for the
charge pump, which generates the Vgs_hs. The low drop linear regulator provides 3.5 mA average current per driver stage. If typically VCC2
exceeds 14.5V the output is limited to 14V.
Charge Pump
The charge pump generates the high side driver supply voltage ( Vgs_hs), buffered at CCP_OUT. The basic circuit (Fig 7), shows
charge pump without load:
Figure 7. Charge Pump Basic Circuit
When the oscillator is in low state (1), Ccp is charged through D2 until its voltage reaches Vbat-Vd2. When the oscillator is in high
state (2), Ccp is discharged though D1 in Ccp_out, and final voltage of the charge pump, Vcp_out is Vbat+VLR_OUT - 2Vd. The frequency of
the MC33253 oscillator is about 330 kHz.
