PIN DESCRIPTION

Table 2-1 details the description of pins in HV892.

Refer to Package Type for the location of pins.

TABLE 2-1:

PIN FUNCTION TABLE

Description

Number Name

GND1 Ground for the DC–DC converter. Connect GND1 and GND2 close to the IC.

VIN Input voltage. Bypass with a 2.2 µF capacitor to GND1.

SCL Clock for the I²C interface. The HV892 is a Fast mode device (f_SCL≤ 400 kHz).

Serial data for the I²C interface. The HV892 is a write-only device with a single 8-bit command

byte. (Refer to Table 3-1.)

SDA

VDD Externally supplied reference voltage for the I²C logic levels. Connect to the I²C bus supply.

GND2 Ground for the IC, except the DC-DC converter. Connect GND1 and GND2 close to the IC.

OUT2

OUT1

Outputs of the H-bridge driver. The liquid lens connect these two pins. When disabled

(AMP = 00h), both of these outputs are held at ground.

Not connected

High-voltage DC output of the internal boost converter. Connect a 4.7 nF 100V ceramic capacitor

to ground close to the IC.

Note 1: Exposed backside pad is at ground potential and should be connected to circuit ground.
