HV57009 64-Channel Serial to Parallel Converter with P-Channel Open Drain Controllable Output Current Features ► ► ► ► ► ► ► ► General Description HVCMOS® technology 5.0V CMOS Logic Output voltage up to -85V Output current source control 16MHz equivalent data rate Latched data outputs Foreward and reverse shifting options (DIR pin) Diode to VDD allows efficient power recovery The HV570 is a low-voltage serial to high-voltage parallel converter with P-channel open drain outputs. This device has been designed for use as a driver for plasma panels. The device has two parallel 32-bit shift registers, permitting data rates twice the speed of one (they are clocked together). There are also 64 latches and control logic to perform the blanking of the outputs. HVOUT1 is connected to the first stage of the first shift register through the blanking logic. Data is shifted through the shift registers on the logic low to high transition of the clock. The DIR pin causes CCW shifting when connected to VSS, and CW shifting when connected to VDD. A data output buffer is provided for cascading devices. This output reflects the current status of the last bit of the shift register (HVOUT64). Operation of the shift register is not affected by the LE (latch enable), or the BL (blanking) inputs. Transfer of data from the shift registers to latches occurs when the LE input is high. The data in the latches is stored when LE is low. The HV570 has 64 channels of output constant current sourcing capability. They are adjustable from 0.1 to 2.0mA through one external resistor or a current source.

Since IOUT = IREF = VREF REXT Given IOUT and VREF, the REXT can be calculated by using: Therefore: If IOUT = 2.0mA and VREF = -5.0V → REXT = 2.5KΩ. If IOUT = 1.0mA and REXT = 1.0KΩ → VREF = -1.0V. REXT = If REXT >10KΩ, add series network RD and CD to ground for stability as shown. V VREF = REF IOUT IREF The intersection of a set of IOUT and VREF values can be located in the graph shown below. The value picked for REXT must always be in the shaded area for linear operation. This control method has the advantage that VREF is positive, and draws only leakage current. If REXT > 10KΩ, add series network RD and CD to ground for stability as shown. This control method behaves linearly as long as the operational amplifier is not saturated. However, it requires a negative power source and needs to provide a current IREF = IOUT for each HV570 chip being controlled. Note: Lower reference current IREF, results in higher distortion, ∆ICS, on the output. If HVOUT ≥ +1.0V, the HVOUT cascode may no longer operate as a perfect current source, and the output current will diminish. This effect depends on the magnitude of the output current.
