Description
This LSP2916 16-channel, high-voltage (HV) driver
is targeted for microoptomechanical systems. Each
device contains 16 high-voltage amplifiers with an
output voltage range of 0 V to 298 V. Internal gain-
setting resistors provide a fixed gain of 32 V/V,
thereby minimizing external component count. Each
amplifier can output up to 300
A, ideal for deflection
and control of optical MEMS mirrors. Output current
limit is programmed by an external resistor.
Additionally, careful attention was paid to minimizing
offset drift and gain variation over temperature. The
internal block diagram is shown in Figure 1. There
are two versions, version A (LSP2916A) and version
B (LSP2916B). For version A, R
F
= 8 M
and
R
IN
= 250 k
; and for version B, R
F
= 8.25 M
and
R
IN
= 125 k
. So LSP2916A has the fixed gain of
32 V/V and LSP2916B has the fixed gain of
66 V/V.
The LSP2916 requires one negative high-voltage
power supply (V
HN
) and one positive 5 V analog
power supply (V
LP
). Corresponding to the 16
channels, there are 16 negative input voltage pins,
INx (x = 1, 2, . . .
, 16), and the corresponding 16
output pins, OUTPUTx
(x = 1, 2, . . .
, 16).
+IN is the noninverting input for all 16 amplifiers,
which means all the amplifiers share the same
noninverting input. +IN should be connected to GND
for typical applications. I
BIAS
pin will set the current
limit for the amplifiers by connecting it to an external
resistor. The LSP2916 is available in a leaded
surface-mount 64-pin MQFP package.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings
can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the
device is not implied at these or any other conditions in
excess of those given in the operational sections of the
data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.
Table 3. Absolute Maximum Ratings
Handling Precautions
Although protection circuitry has been designed for this
device, proper precautions should be taken to avoid
exposure to electrostatic discharge (ESD) during
handling and mounting. Agere Systems Inc. employs a
human-body model (HMB) and charged-device model
(CDM) for ESD-susceptibility testing and protection
design evaluation. ESD voltage thresholds are
dependent on the circuit parameters used in the
defined model. No industry-wide standard has been
adopted for CDM. However, a standard HBM
(resistance = 1500
, capacitance = 100 pF) is widely
used, and therefore, can be used for comparison
purposes. The HBM ESD threshold (>500 V) presented
here was obtained by using these circuit parameters.
Application Notes
LSP2916 is recommended for MEMS optical systems.
It features programmable current limit while the output
can swing up to 298 V. With all the feedback resistors
inside the chip, there is
no more need for these resis-
tors in the external circuit.
Safety Handling for the High-Voltage Device
LSP2916 is designed to operate up to 298 V negative
power supply, so special care should be paid to safety
issues.
Bypass Capacitors/Protection Series Resistor for
the Power Supplies
To minimize noise coupling to the output, a 0.1
F
bypass capacitor should be placed as close as
possible to all power supply pins. Additionally, to avoid
the possible degradation of the LSP2916 when V
HN
is
hot switched, a 10
series resistor between the V
HN
pin and the V
HN
power supply is required.
