CS5462
1. GENERAL DESCRIPTION
The CS5462 is a CMOS monolithic power mea-
surement device with an energy computation en-
gine. The CS5462 combines a programmable gain
amplifier, two ?? ADC’s, system calibration, and
energy-to-frequency conversion circuitry on a sin-
gle chip.
The CS5462 is designed for energy measurement
applications and is optimized to interface to a shunt
or current transformer for current measurement,
and to a resistive divider or transformer for voltage
measurement. The current channel has a pro-
grammable gain amplifier (PGA) which provides
two full-scale input level options. With a single +5 V
supply on VA+/AGND, both of the CS5462’s input
channels accommodate common mode + signal
levels between (AGND - 0.25 V) and VA+.
The CS5462 has three pulse output pins: E1, E2
and FOUT. E1 and E2 can be used to directly drive
a mechanical counter or stepper motor, or inter-
face to a microcontroller. The FOUT pin conveys
average real power at a pulse frequency many
times higher than that of the E1 or E2 pulse fre-
quency, allowing for high speed calibration.

XOUT, XIN - A single stage amplifier inside the chip is connected to these pins and can be used
with a crystal to provide the system clock for the device. Alternatively, an external clock can be
supplied to the XIN pin to provide the system clock for the device.
CPUCLK - Output of on-chip oscillator which can drive one standard CMOS load.
CAL0, CAL1 - Must be tied to a program select pin for calibration.

FREQ - Must be tied to a program select pin to determine the frequency of E1 and E2.
IGAIN - Must be tied to a program select pin to determine the Full-Scale Input Voltage Range of
the current channel.
RESET - Low activates Reset
E1, E2 - The energy output pin issues a fixed-width pulse train output with a rate proportional to
real energy.
FOUT - Outputs energy pulses at a maximum rate of 10 kHz. Used for calibration purposes.
NEG - Low indicates negative energy.
