ShangHai Consonance Elec · Supervisor and Reset ICs · TSSOP-16

CN1185 from ShangHai Consonance Elec, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN1 input Comparator 1 negative input. Connect directly to the monitored voltage or via an external resistor divider to set the trip threshold. Typical trip threshold 1.22V or 1.256V depending on CHRG.
2 OUT1 output Comparator 1 open-drain output. Pulls low (internal NMOS to GND) when IN1 rises above the upper trip threshold; goes high-impedance when IN1 falls below the lower trip threshold. Pull-down current ≥10mA at OUTx=0.3V.
3 IN2 input Comparator 2 negative input. Connect directly to the monitored voltage or via an external resistor divider to set the trip threshold.
4 OUT2 output Comparator 2 open-drain output. Pulls low when IN2 rises above the upper trip threshold; high-impedance when IN2 falls below the lower trip threshold.
5 IN3 input Comparator 3 negative input. Connect directly to the monitored voltage or via an external resistor divider to set the trip threshold.
6 OUT3 output Comparator 3 open-drain output. Pulls low when IN3 rises above the upper trip threshold; high-impedance when IN3 falls below the lower trip threshold.
7 IN4 input Comparator 4 negative input. Connect directly to the monitored voltage or via an external resistor divider to set the trip threshold.
8 OUT4 output Comparator 4 open-drain output. Pulls low when IN4 rises above the upper trip threshold; high-impedance when IN4 falls below the lower trip threshold.
9 CHRG input Comparator trip-threshold control logic input. High: falling trip threshold typ 1.22V. Low: falling trip threshold typ 1.256V (≈3% higher, for charge-state compensation). Affects all four comparators simultaneously.
10 NC unconnected No connection.
11 HYS1 input Comparator hysteresis setting logic input (LSB). Together with HYS2 selects hysteresis of 1%, 3%, 6%, or 10% of the falling trip threshold. VIL≤0.6V, VIH≥0.7×VDD.
12 HYS2 input Comparator hysteresis setting logic input (MSB). Together with HYS1 selects hysteresis of 1%, 3%, 6%, or 10% of the falling trip threshold. VIL≤0.6V, VIH≥0.7×VDD.
13 GND power_in Negative supply / ground reference.
14 BLINK input Blink control logic input. When a comparator output is low, CHRG=low, and BLINK=high, that output toggles at ~2Hz (50% duty, ~500ms per state) - used to indicate charging in progress via the LED indicator.
15 NC unconnected No connection.
16 VDD power_in Positive supply input, 2.7V to 6V operating range (absolute max 6.5V). Typical supply current 7.3µA at VDD=3.7V.
